It takes Squidward some time to try a Krabby Patty, but once he does he finds out that he loves them. He gets so addicted that he eventually locks himself away and starts overeating. He can’t control himself, and once Spongebob comes knocking, it’s too late. The Krabby Patties have gone to Squidward’s thighs and then he blows up.
