Roo is Kanga's son. Whenever he goes out with his mother, he goes inside her pouch. Roo, like Tigger loves to bounce.
Roo appears in many of the mini-games in 100 Acre Wood. The games he shows up in are Tigger's Giant Pot, Pooh's Muddy Path, Balloon Bounce, and The Exposition. In Kingdom Hearts, he is a big help in the Bouncing Spot page area where he helps Sora by catapulting him into the trees to get special items or Rare Nuts for Owl and he helps Sora with advice with Tigger's challenges.
