Sour Puss appears in the opening of Pac-Man World; he is seen in the kitchen of Pac-Man's home with Ms. Pac-Man. It is unknown what happened to him after Ms. Pac-Man was captured, but he appears in the ending picture alongside the other rescued family members. In the original storyboard, he was going to hiss at the incoming intruder, but he was silent in the final game.
Sour Puss is an orange cat with a round body. He has black strokes of fur on his back and tail. His eyes are slanted, and he has rather angry-looking eyebrows. In Pac-Man World, he is proportioned more like a real-world kitten, and had wide-open eyes; he was also a more yellow-ish color.
