Plankton is one of the animated characters in the cartoon series, SpongeBob SquarePants; he is the owner of the Chum Bucket restaurant competing for customers with Krabs’ rival business. The full name of this queer character is Shedon J. Plankton but it is only disclosed in the episode, Plankton’s Army. He is married to a computer, but not even his wife, Karen, knows his full name. When she finds out she laughs at Plankton, but without being mean. All throughout the series Plankton will try to get his hands on Mr. Krabs’ secret recipe.
Sheldon Plankton plays the smallest of the heroes in SpongeBob SquarePants, he is so tiny that he can fit into SpongeBob’s hand. He is a zooplankter with one eye in the center of his head that is easily recognized by his very deep voice. There is one funny episode, Enemy-in-Law, when Plankton nearly becomes Mr. Krabs’ stepfather in a very funny context that viewers definitely like. In the movie version of the animation, Plankton finally succeeds in stealing the Krusty Krabs’ secret recipe and he is the happiest zooplankter in the world. Unfortunately, SpongeBob ruins his dream of world domination.
There is a lot of contradiction between Plankton’s humble tiny appearance and his aspirations and goals. This small, jelly, green bean-shaped creature with long antennas is 1% good and 99% evil. The flaws of his nature keep him away from getting hands on the Krabby Patty formula, because he makes stupid mistakes out of impatience and too much haste. Sneaky and jealous, Plankton ignores the fact that he and Mr. Krabs used to be friends, with Krabs as his only protector against those who bullied him. His anger is often targeting SpongeBob whom he thinks to be too silly and babyish, and who on top of everything has the privilege of knowing the ingredients of the Krabby Patty recipe.
We could say that there is no antagonist or villain in the SpongeBob SquarePants series other than Plankton ^(http://www.indiefilmhouse.com/goto/http://www.spongetoysbob.com/). He makes all sorts of major schemes to achieve his goals and most of the time gets involved with characters that are a lot stronger than him; a very large ego surely hides in that tiny body of his. From a certain point of view, Plankton ^(http://www.indiefilmhouse.com/goto/http://www.spongetoysbob.com/spongebob/category/spongebob-reviews/spongbob-puzzles/) wins viewers over by his miserable failures at getting something that seems so important for him. No matter the way one feels towards this character it is obvious that he gives a grain of salt to the cartoon.
