Tubenks

Tubenks is a fictional creature that appears in the animated television series SpongeBob SquarePants. It is a small, gelatinous, blue, blob-like organism with two beady eyes and a single, large, suction-cup-like mouth. Tubenks are known for their ability to absorb and consume almost anything, including food, furniture, and even other sea creatures. Despite their voracious appetite, they are generally depicted as harmless and even somewhat endearing.

Tubenks first appeared in the episode "Graveyard Shift," where they were shown to be a nuisance to SpongeBob and Squidward at the Krusty Krab. They were later featured in other episodes, often as background characters or as a source of comedic relief. In some instances, Tubenks have been shown to possess surprising intelligence and even have the ability to communicate through a series of gurgles and squeaks. Their unique physiology and insatiable hunger have made them a memorable part of the SpongeBob SquarePants universe. The creature's design is simple yet effective, contributing to its distinct and easily recognizable appearance.
