Tigger

Tigger is a friend in the 100 Acre Wood. He made his first appearance in Kingdom Hearts, alongside with Roo to train Sora how to "jump", which requires jumping on a specific tree coordinate and reach to the finish line. Tigger mostly uses Rabbit's farm as a jumping spot, therefore ruining his vegetables, much to Rabbit's chagrin.

Tigger's original voice actor, Paul Winchell, was already long retired even before the Kingdom Hearts series was conceptualized and did not reprise the role, all the more in II as he had already died in the time period between the releases of Kingdom Hearts and Kingdom Hearts II. Tigger is instead voiced in both games by Jim Cummings, his current official voice-actor, who also in the games voices Winnie the Pooh, Pete and others.

Kingdom Hearts
''Tigger loves to bounce more than anything. Sometimes his bouncing gets out of hand, but he doesn't mean any harm. Beneath that happy-go-lucky exterior beats a sensitive, gentle heart. He bounced onto the scene in "Winnie the Pooh and the Blustery Day" (1968).''
