What is that boy name on sponge bob he put pickles. Under his tinge?

You're likely thinking of Plankton, the villain from SpongeBob SquarePants. Plankton is known for his obsession with stealing the Krabby Patty formula, and he often uses his tiny robotic assistant, Karen, to help him.

Plankton doesn't put pickles under his "tinge," but he is frequently seen with a pickle under his nose. This is a recurring gag in the show, and it's a humorous representation of his generally unsuccessful and often desperate efforts to get ahead.
