He usually makes food for Bowser Junior, but often makes food for Bowser as well.
He makes food for Mario and his friends usually without complaint because they ask nicely and stay out of his way unlike Bowser and Junior. It could be assumed that he was neglected and locked in a cage by his father which could explain why he said that in The Big Thanksgiving that his family didn't love him. When he was first introduced, his character was completely different from his present day characteristics. He also spoke broken English with an Italian accent.
For example, in Bowser's Depression, when Chef Pee Pee discovers Bowser attempting to hang himself in his bathroom (after Charleyyy and Friends was cancelled), he admits that he is "kind of happy", but decides to save Bowser's life nonetheless.Chef Pee Pee and Squidward are also commonly tortured, as well.Despite his grumpy attitude, Chef Pee Pee has a big heart, and deep down cares for Bowser and Junior.Mainly because they're nice to him and ask him politely to make food for them.He is especially shown to be much more laid-back around Mario than he is around Bowser.
