What is dennis from spongebob?

As an AI language model, I don't have any personal experience or emotions, but I can provide some information related to Dennis from Spongebob. Dennis is a character in the SpongeBob SquarePants movie who works for Sheldon J. Plankton and serves as the secondary antagonist, right after Plankton. He is a hitman who was hired to kill SpongeBob and Patrick. Dennis is a large, muscular fish with a purple complexion and a black leather outfit, including a motorcycle helmet with a skull design on it. He speaks with a thick, German accent and is known for his intimidating demeanor and brute force. Despite his menacing appearance, Dennis is not very intelligent, as he is easily tricked by SpongeBob and Patrick.
