Cheese was irritable and short. He strongly hated Orange and his puns. He also attempted to be nice to Orange, since he tells him that he's not playing his game.
Cheese hated Orange (who is Cheese's worst enemy) way too much (with his puns) since they firstly met. Orange then proceeded to say puns until Cheese finally snapped and started singing a song in order to prevent listening to Orange, but still, he is annoyed by Orange as Orange then sing with him, until he wanted an extremely worst nightmare. He became overjoyed when Dane Boedigheimer grated him with the cheese grater. But, survives and then cried when he got annoyed by Orange again as a cheese pizza, possibly to regret his actions to cause his death.
