SpongeBob: Weee! Gotchya! There you go, little fella. [To Patrick] Say, Patrick. Don't you think that Jellyfish Fields has gotten bigger today?
Patrick: I don't know, but all of this failure is tiring me out. I'm just gonna take a nap on that rock right over there.
SpongeBob: Okay, Patrick. I'll go see if there are any jellyfish in that creepy, scary, evil-looking cave over there.
[Evil Alien Jellyfish Overlord is shown]
SpongeBob:[Catches a jellyfish] Aw. You're the charms. If only you didn't sting, you'd make the perfect pet! [Jellyfish stings SpongeBob] Oh, well! I guess it's catch and release for now.
[Evil Alien Jellyfish Overlord catches a jellyfish and turns it into a Jellion; soon the Overlord makes more Jellions. Patrick is shown sleeping. The Jellion engulfs Patrick's entire body and creates a Jellion Patrick. Some Jellion's take the real Patrick away. Tentacles extend out of Jellion Patrick's mouth and place Patrick's jellyfish net in Jellion Patrick into his hand]
SpongeBob:[steps in front of Patrick] Isn't he the cutest little jellyfish you've ever seen. [picks up Jellion jellyfish by the stingers] And he doesn't sting.
[Jellion Patrick captures numerous jellyfish in his net]
SpongeBob:[looking at Jellion jellyfish] You don't suppose this is some sort of new breed, huh? [places Jellion jellyfish back into net] I think I'll keep this one as a pet. [spots Patrick's overfilled net] Whoa!
Jellion Patrick: Yes. I too have caught many jellyfish. [holding up index finger] Perhaps we shall give one to each of our friends. [grins and breaths heavily]
SpongeBob: Wow, Patrick! That's a great idea.
[Bubble transition to Squidward's house at night]
SpongeBob: Well, we've given a jellyfish to everyone, except Squidward. I'm sure he doesn't want one.
Jellion Patrick: He'll take one and like it. [shoves the Jellion into the mail slot. The Jellion creates a clone] Pleasent dreams square one.
SpongeBob: Hah, back at ya good buddy. [Jellion Squidward is behind him]
Jellion Squidward: Don't let the bed bugs bite. Ha ha ha.
SpongeBob: Um, that's some good advice. Good night, Squidward.
Jellion Squidward: There will be plenty of biting this night. RAH!
SpongeBob:[To Jellion] Tonight, you'll sleep with me little jelly. Goodnight, jellyfish. Goodnight, Gary! Heh, good night little jelly. [SpongeBob sleeps. The Jellion tries to climb on SpongeBob, but he wakes up] Ah, I can't sleep. [walks downstairs. The Jellion follows him. SpongeBob is watching a horror film and eating popcorn. The Jellion tries to climb on SpongeBob again, but he screams. The Jellion tries to climb on him, once again] Oh, you want some popcorn? Here ya go. [tosses popcorn into the Jellion's mouth, causing it to choke] Hey, hey! Are you okay?
[Bubble transition to morning. The Jellion is shown sleeping]
SpongeBob: Aw, look at him, the little angel. Guess he couldn't make it past the third feature. [picks up the Jellion] Good morning sleepy-head. We wouldn't want anything to happen to you while I'm at work. [puts the Jellion in a cage] You better stay in here where it's safe. [pats Gary's shell] You two stay out of trouble, bye!
[SpongeBob leaves his house and Gary takes a nap near a plant. The Jellion then eats Gary and the plant at the same time creating Jellion Gary which looks like Gary mixed with a plant. Bubble transition to SpongeBob walking into the Krusty Krab]
SpongeBob: Woah! Look at all of the customers!
Jellion Clone: One Krabby Patty, hold the mayonnaise.
Jellion Squidward: One Krabby Patty, hold the mayonnaise.
Jellion Patrick:[holds out a tray with a Krabby Patty] One Krabby Patty, hold the mayonnaise.
Jellion Squidward:[takes the tray with the Krabby Patty and gives it to the Jellion Clone] Thank you, come again.
[Jellion Squidward and the Jellion Clone both yell out "RAH" and the next customer who appears normal walks up]
Normal Fish: I would like one Krabby Pat-
Jellion Squidward:[takes out another Krabby Patty] One Krabby Patty, hold the mayonnaise. RAH!
Normal Fish: Ugh. Actually I want one with extra mayo!
[Jellion Squidward and the rest of the Jellion Clones begin hissing and pointing at the lone, normal fish]
Normal Fish: W-what's wrong dudes?
Jellion Mr. Krabs:[comes out of Mr. Krabs' office] I'm sorry valued customer. We are currently out of the condiment you call mayonnaise. [takes out a Jellion] Please accept this free jellyfish hat instead! [puts the Jellion on the normal fish's head] Thank you, come again! [leaves].
SpongeBob:[looks confused] Huh? That's funny. We just received a whole shipment of mayonnaise. [walks to the back and spots Jellion Patrick] Patrick?!? What are you doing? Cooking Krabby Patties is my job.
Jellion Patrick: I am here to replace you and all of your kind!
SpongeBob:[laughs] I saw that movie last night, too. Woops! If you're going work here, you're going to need an offical Krusty Krab hat.
Jellion Patrick: Hat? [grows a Krusty Krab hat on his head]
SpongeBob: Say, that's a pretty neat trick! I'm going to get some extra mayonnaise from the back.
Jellion Patrick:[quickly turns around with his torso still facing the grill] NO MAYONNAISE!!! [uses his mouth tenticles to eat the Krabby Patty SpongeBob was holding then turns back around to cook more Patties].
SpongeBob: O...kay? [walks into the freezer] He's acting weird today. [spots the boxes of mayonnaise] Hey! There's plenty of mayo back here! [hears a strange noise] Huh? Is somebody in there? [looks into the back and spots the Evil Alien Jellyfish Overlord, Jellions, and all of the citizens trapped in pods] Monsters! Huh? Squidward and Mr. Krabs! Patrick too! [spots Harold] And some random guy! Huh? AHH! My spatula! It's just like that movie I watched last night! Those things have captured everyone and put them into creepy pods. [walks out of the freezer nervously walking past Jellion Patrick] Hi, uh, Patrick? I gotta...clean the tables...Patrick. Ha ha...Patrick. [walks out backwards with Jellion Squidward then surprising him].
Jellion Squidward: Hi SpongeBob! Don't you want this cute little jellyfish? [the Jellion then hisses at SpongeBob].
SpongeBob: Ha ha...uh, no thanks. [continues walking backwards and bumps into Jellion Mr. Krabs] Ah! Mr. Krabs!
Jellion Mr. Krabs: You seem tired SpongeBob. Why don't you go home and take a nap. [hisses strangely at SpongeBob].
Jellion Squidward:[still holding a Jellion] Yes, and you can use this jelly as a pillow.
SpongeBob: Oh, that's okay. I-I have one at home. Hah...[continues walking backwards until he is scared off by more Jellion Clones until he reaches the door].
Jellion Squidward and Jellion Mr. Krabs: Sleep well.
SpongeBob:[continues walking backwards until he bumps into Jellion Harold]
Jellion Harold: Re-
SpongeBob: AH! Random guy! [starts running from a bunch of Jellions until he loses them by hiding behind a rock]. What am I going to do? All of my friends taken by those Jelly creatures. I can feel their creepy, rope-like tenticles now! [suddenly is roped and drag into Sandy's tree dome and is locked down].
Sandy: Alright you rotten jelly clone. What have you done with SpongeBob.
SpongeBob: I'm no clone Sandy. I am SpongeBob.
Sandy: Then you won't mind if I run a simple test. [starts tickling him and he starts laughing hysterically] You're SpongeBob alright.
[Bubble transition to where SpongeBob is free]
SpongeBob: What are we going to do Sandy?
Sandy: If only we knew the Jellion's weakness.
SpongeBob: Well the only thing I know is that they can't stand mayonnaise.
Sandy: Ew, I don't like mayonnaise neither.
SpongeBob:[looks suspiciously at Sandy] Oh, so you don't like mayo? Just like a Jellion!
Sandy:[smacks SpongeBob] Oh, snap out of it SpongeBob! Now if only we had some mayonnaise.
SpongeBob: There's lot at the Krusty Krab! But we'll never get past THEM! [points to a bunch of Jellion Clones just outside the dome].
Sandy: Not to worry! [takes out glasses that looks like the Jellion's eyes] We'll be in disguise.
[They both walk outside the dome whistling as they walk up to a Jellion Clone]
Sandy: Greetings fellow Clone. I hate mayonnaise.
SpongeBob: I hate mayonnaise and mustard.
Jellion Clone:[looks suspiciously at SpongeBob] Hmm...
[SpongeBob and Sandy both walk off whistling]
Jellion Clone: I like mustard!
[They both walk into the Krusty Krab and meet up with Jellion Mr. Krabs]
Jellion Mr. Krabs: Did you take that nap SpongeBob?
SpongeBob: Uh huh! Sure did!
Sandy: Yep. We're all rested and jelly-fied.
SpongeBob:[laughs nervously and elbows Sandy accidently knocking off her Jellion glasses] Good one Jellion Sandy.
Jellion Mr. Krabs: IMPOSTERS!!!
[All of the Jellion Clones in the Krusty Krab begin hissing and surrounding SpongeBob and Sandy]
Sandy: SpongeBob! The mayonnaise!
SpongeBob:[leaps up high and swings over to the condiment stand and grabs a jug of mayonnaise then squirts one at Jellion Mr. Krabs]
Jellion Mr. Krabs: AH! [the mayonnaise lands on him] Ew...[he then disaggrantes which frees the real Mr. Krabs from his pod].
Sandy: It worked SpongeBob! Keep going!
SpongeBob:[squirts Jellion Squidward who tried to attack him with mayonnaise destroying him and freeing Squidward in the process].
Sandy: SpongeBob! Look out!
[All of the Jellion Clones begin to close in to which SpongeBob squirts and destroys all of them. SpongeBob and Sandy then head towards the back running past Jellion Patrick]
SpongeBob: Oh, hi Jellion Patrick!
Jellion Patrick: Hold the mayonnaise!
SpongeBob: Doh! Almost forgot! [squirts Jellion Patrick with the mayonnaise causing him to disaggrante and frees Patrick from his pod].
Patrick:[falls on his neck] Doh! Hey guys! What's shaking? [Squidward points to the Evil Alien Jellyfish Overlord] Oh...
[SpongeBob and Sandy enter the freezer to confront the Overlord]
Sandy: Hold it right there you evil blob of slime! You're through 'cause we know your weakness! Show 'em SpongeBob!
[SpongeBob shows the Overlord the jug of mayonnaise. The Overlord then roars loudly telling the Jellions to attack SpongeBob and Sandy]
Sandy: Let 'er rip!
SpongeBob:[starts squirting the Jellions until the jug of mayonnaise starts to act up] Nah! Gasp! Sandy! It's so cold in here the mayonnaise is starting to freeze!
Sandy: Then hurry and throw it SpongeBob!
SpongeBob: Aye, aye! [unscrews the lid of the jug of mayonnaise and hurls it at the Overlord but it freezes and lands on it's head. Then it laughs at SpongeBob's failure] Oh no! This mayonnaise is frozen solid!
Sandy:[next to a thermostat] Then I'll just turn up the heat! [turns the thermostat from "COLD" to "HOT" causing the mayonnaise to melt on the Overlord's head thus destroying him all of the Jellions].
SpongeBob and Sandy: Hooray!
Mr. Krabs: What happened?
SpongeBob: Well, let me tell ya!
[A time card that says "Eleven Minutes Later" is shown]
SpongeBob: And that's why we're covered in goo!
Mr. Krabs: Thanks for rescuing us SpongeBob. But what are we going to do with all of this green slop?
Patrick:[tastes the green goo] Mmmm! Freaky Clone Jelly Relish!
[Bubble transition to the Krusty Krab again]
Mr. Krabs: Relish Patties! Get your Freaky Clone Jelly Relish Patties! Only 4 bucks extra!
Patrick:[to Squidward] Uh, I'll have one Relish Patty. Hold the mayo.
[SpongeBob looks suspiciously at Patrick with the next time card saying "The End?" ending the episode]
