Eugene H. Krabs is one of the main characters in the SpongeBob franchise, and owner of the Krusty Krab. One of Mr. Krabs' most notable and infamous personality traits is his love for money and inability to spend it. As such, this often puts him at odds with friends and family, most prominently with Squidward Tentacles. He is often at loggerheads with Sheldon J. Plankton over the secret Krabby Patty formula.
