Abu

Abu is Aladdin's pet monkey. He is often seen getting into constant trouble every now and then because of his bad habit of stealing things. He was first seen in Disney's "Aladdin".

Kingdom Hearts
''Aladdin's faithful furry sidekick. Abu's size and ability make him valuable in tight spots. He's got a weakness for jewels and treasure, and when he's around them he can't think of anything else.''

He was all monkey-business in "Aladdin" (1992).

Kingdom Hearts II
Aladdin (1992)

''Aladdin's faithful and rather furry sidekick. Abu doesn't talk a lot, but he always understands what Aladdin needs.''

Unfortunately, Abu can't resist treasure, even if it belongs to somebody else.

Kingdom Hearts
In the first game, Abu is first seen trapped in a sand pit whith Aladdin. They manage to get out and help out Sora and co. Abu only appears on occasion, whenever Sora and Aladdin need him to help solve a puzzle in the Cave of Wonders.

Kingdom Hearts II
In this game, Abu is again getting into trouble when he steals a black lamp from the Peddler's shop. Aladdin forces him to give the lamp back, only to discover moments later that it was the lamp Jafar was trapped into. Abu follows Aladdin, Sora and co. to the Cave of Wonders, so they can obtain some treasure to purchase the lamp. Abu activates a trap when he grabs a floating gem, but quickly helps Sora to solve the puzzle.

After the group defeats the Blizzard Lord and the Volcanic Lord, Abu tries to get away with a gem he swiped from the Cave, but Donald takes it from him and tries to keep it for himself.

Aladdin
Abu is Aladdin’s Pet monkey and sidekick friend who helps his master steal goods from the market as they are very poor and have no money at all. When Aladdin and Abu meet the Blue Genie of the Lamp, The Genie changes Aladdin into a prince and Abu, a royal elephant.

Return of Jafar and Aladdin and the King of Thieves
Abu appears again in the two Aladdin sequels named above, reprising his role as Aladdin’s sidekick, although, this time, due to Aladdin’s marriage to Princess Jasmine , he no longer steals.
