SpongeBob is waiting at the bus stop to go to Glove World. He promised Patrick that they would be first in line, and to be first to get on the bus. Then a lot of fish come and cut in front of him. Patrick comes and asks SpongeBob why he is not first (like he promised). Sandy comes and ask SpongeBob for him to do "Operation Acorn Smoothie". Patrick goes to Glove World without SpongeBob. After that, he goes back to the bus stop, then Mr. Krabs asks SpongeBob to say no to Pearl about the new shoes.
He then goes back to the bus stop and helps Grandma SquarePants cross the road. Patrick returns and tells SpongeBob that sometimes he just has to say no, then asks SpongeBob to scratch his back. He is shown at his house crying about how he can't say no to anything anyone asks him. Gary then goes to a catalog and orders something for SpongeBob. The package arrives and says "Abrasive Sponge". He sticks it on his back.
He goes out and Pilar asks him to carry his groceries for him. His body switches 180 degrees, showing the abrasive side and says "Carry it yourself, fish-face" for SpongeBob. He does the same for Larry the Lobster, Grandma, and Sandy. He then goes into the Krusty Krab, then Mr. Krabs asks him to do a seventeen hour extra shift. SpongeBob says yes, but then his abrasive side says no, unless Mr. Krabs pays for overtime, being paid more than the standard wage for coming in over his contracted hours. Mr. Krabs goes to his office to look up the meaning for "overtime" - then is shocked that SpongeBob could use such a disgusting word. He goes home and Squidward says not to annoy him. SpongeBob's abrasive side says the complete opposite that SpongeBob would normally say, then Squidward gets happy and hugs him, saying: "You don't know how long I have waited to hear those words."
Patrick says it's time for their play-date. SpongeBob talks and so does his abrasive side, confusing Patrick, eventually scaring Patrick into believing that SpongeBob's face is haunted. SpongeBob goes into his house to the bathroom and stares into the mirror, and realizes whats wrong - that his abrasive side is getting out of control. He asks Patrick and Mr. Krabs for help, but his abrasive side gets the best of him. He goes to Sandy for help, then explains what happened and why he got an abrasive side. Sandy then rips it off his back, while SpongeBob holds Patrick, then is shown with intense pain for a short while as Sandy rips the abrasive side off. Sandy puts it in a box labelled "Return to sender" and puts it in the mailbox. The green skin growls. SpongeBob then remembers to go say sorry to Grandma. He goes, then it turns out that Grandma has an abrasive side now too, much to SpongeBob's horror. The episode ends with SpongeBob screaming.
This is the third time SpongeBob becomes or acts mean. The first was in "Plankton!", and the second was in "Walking Small". However, the reason for him becoming mean does not have to do with Plankton, as it did in the previous two episodes.
The scene where Squidward said "You don't know how long I've waited to hear those words!" is sped up in the promo, most likely to shorten the promo.
SpongeBob tells Squidward that he wouldn't hang out with him for all the money in Mr. Krabs's mattress. This is possibly a reference to the episode "The Lost Mattress", since that episode reveals that Mr. Krabs keeps his money in his mattress.
Howard Blandy makes a cameo appearence standing in front of SpongeBob in line.
SpongeBob's Abrasive Side speaks with a sterotypical New Jersey accent.
This is the second time that Pearl's voice was heard but she was not seen.
Two versions of SpongeBob are available as playable fighters in Super Brawl 3; Normal SpongeBob, and SpongeBob with the abrasive side, named Abrasive SpongeBob.
This, along with its sister episode, Earworm, both involve with something attached to SpongeBob's body but was later removed near the end. For this episode, the abrasive side is found in SpongeBob's back, and in Earworm inside (internal) SpongeBob's ear whereas in the latter's case as well as both episodes ending in characters screaming.
