According to Plankton, its actual purpose is to open things as easy as a clam.
Plankton's plan was to use the bubble to threaten Mr. Krabs into giving Plankton the Krabby Patty Secret formula because according to Sandy, the Super Goo was toxic and could destroy things. Plankton nearly succeeds with getting the formula, but it was just a stick of dynamite rolled in a piece of paper. Once he got the fake formula, before knowing it was fake, he went against his deal with Mr. Krabs and popped the bubble, however, the super goo did not destroy things, but instead it just covered the town and its inhabitants in the super goo.
It was destroyed when it hit the roof of the Chum Bucket after the dynamite went off.
It was the first form seen in the episode. Unlike the other forms, it was red.
It was the second form seen in the episode.
Like its other forms, except the bucket form, it was pink and purple.
It was the third form seen in the episode.
It was the form that was used to open the crack at the bottom of Goo Lagoon. To do so, it expanded the two sides of the Clam form.
It was the fourth form seen in the episode.
It detaches from the Clam Digger to be created.
It was the first form that was controlling the Super Goo Bubble by using arms that it has. However, Plankton had to change forms because Sandy, Patrick, and SpongeBob in Sandy's submarine found him and started to chase him.
The second time it was shown, it had an electrical plug that when it connected to the super goo bubble, it shocked anyone who was on the bubble.
It looks similar to the next two forms on the list.
It was the fifth form seen in the episode.
It was created when Plankton had to change from the flying mode by replacing the propeller to track wheels.
Sandy, Patrick, and SpongeBob in Sandy's submarine chased Plankton in the tank form of the vehicle until he sped up. Then, Sandy took her lasso and lassoed up the tank and wrapped the end that she was holding to a hook in front of her. SpongeBob, Patrick, and Sandy ran to the vehicle. Then, Plankton changed forms back to the flying form.
This is not technically the name of the form, but rather what it did, controlled the Super Goo Bubble.
It was the sixth and final different form seen in the episode.
It was created when the flying mode landed in the goo.
It had a giant needle that Plankton used to pop the super goo bubble. It also had a parachute.
