Pac-Bears are enemies in the Forest area of Pac-Man World 2. As their name suggests they are a Pac-Version of Bears. During their infancy they are called Pac-Cubs. They are big creatures that mainly appear in the forest but there are a few Polar Pac-Bears on Snow mountain. Pac-Man can only defeat them when they face his direction and he has to rev roll him in the face.
"The Pac-Bear is one of the largest natural creatures in Pac-Land and has little to fear. Pac-Bears are large enough to eat any of the Pac-People, but prefer to play with their food before eating it. Pac-Bears can be found in various climates."
