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, had 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, Cheshire Cat 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).

Kingdom Hearts: Chain of Memories
''The one and only. Cheerful Tigger loves to bounce all day long.''

Sometimes his energy is too much for the others, but he always means well.

Kingdom Hearts II
Winnie the Pooh and the Honey Tree (1966)

''Tigger sure is energetic. He loves to use his tail to bounce all over the Hundred Acre Wood. Sometimes his bouncing gets to be a bit much, but he doesn't mean any harm. Underneath that happy-go-lucky exterior, there's a sensitive, gentle heart.''

Kingdom Hearts
In Kingdom Hearts, the mini-game with Tigger ("Block Tigger") takes place in Rabbit's House; Sora is required to block Tigger from jumping on Rabbit's crops. If Tigger does jump on Sora's head or shoulders, Sora earns points. There is a "Rush" function at the bottom of the command menu, which enables Sora to get to Tigger on time (i.e. before he jumps on Rabbit's crops and pushes them down). He is also in the Giant Honey Pot Area. You have to follow Tigger's exact path across the area. If you fall or go to the wrong spot, you have to start over. Then he is in the minigame "Tigger's Giant Pot", where you have to whack the nuts back at the pot. When you successfully hit the pot, Tigger leaps up in the air. Tigger also is seen before the Pooh's Swing mini-game, when you talk to him he says his bouncing spot disappeared as well as Eeyore's tail.

Kingdom Hearts II
The Kingdom Hearts II mini-game involves Tigger and Roo, and it also takes place in Rabbit's House. This game also involves bouncing, but this time, Sora is required to bounce on rows and rows of balloons. Each balloon, if burst, gives Sora a number of points (in the form of yellow orbs). Also, he is one of the few allies who helps you get through the Spooky Cave mini-game.

Trivia

 * In the original Disney version of Winnie the Pooh, Tigger was originally to be like Shere-Khan, the tiger in the Jungle Book. He was originally evil and cunning, but they changed him to hyper and excited, due to the fact the movie was family-friendly.
