The Giant Super Goo Bubble was a purple super goo bubble that made it's first and so far only appearance in the episode "It Came from Goo Lagoon."
The Giant Super Goo Bubble was a purple, sticky, semi-solid malleable bubble made of Super Goo. It seems to be very light since Plankton's robot was able to push it easily.
It was created when Plankton, using his Mechanical Clam Digger, opened a small crack that was releasing small Super Goo bubbles. The Super Goo rose to the surface and created the Super Goo Bubble. Sandy thought that Super Goo was toxic and would destroy everything, but after Plankton used the Clam Digger to pop the Super Goo bubble it just cover things and creatures with the goo. Before it popped, the bubble was used as a threat by Plankton to Mr. Krabs to give Plankton the formula. SpongeBob tried to stop the Bubble by using Giant Bubble Fun, a giant bottle of Bubble Soap that comes with a giant bubble blower, to create a Bubble Giant. The giant was destroyed when Patrick got in its way and it stepped on him, which created a hole. It flew away, but came back and lifted the bubble away. However, the giant was slowly destroyed when the bubble went up into the air. The bubble bounced off of the moon and came back to Bikini Bottom.
