Dumbo

Dumbo is a Summon that appears in Kingdom Hearts and Kingdom Hearts: Chain of Memories. He is originally from the Disney movie "Dumbo".

Kingdom Hearts
''A baby circus elephant. He was taunted because of his huge ears, but his talent for flying made him the star of the '' circus.

''Ascend with button, descend with  button. Attack: Splash. Cost: 3 MP.''

He first flew onto the screen in "Dumbo" (1941).

Kingdom Hearts: Chain of Memories
A small elephant born in a circus.

The other animals laughed at his big ears, but the courage to fly made Dumbo the star of the circus.

If Sora calls, Dumbo will come to the rescue.

Kingdom Hearts
Dumbo survived the destruction of his homeworld, but only as the Watergleam Gem, which wound up in Monstro where it was found by Sora. Sora took the gem to the Fairy Godmother in Traverse Town, and she activates the gem to allow Dumbo to assist Sora as a summon.

Abilities
When summoned, Dumbo hovers in midair with Sora riding on his back. The two are invulnerable to harm until Dumbo is dismissed or runs out of MP. Dumbo blasts a jet of water from his trunk at the enemies, drenching them, pushing them backwards or defeating them. Dumbo can also ascend and descend in flight. Dumbo is a useful Summon and is best used when surrounded by Heartless.

When Sora summons Dumbo in Neverland, Dumbo is able to fly freely in the air instead of just hovering around. Sora shrinks to a smaller size to ride Dumbo during this summon.

In Kingdom Hearts: Chain of Memories, Dumbo appears as a Summon Card as a reward for completing Monstro. In the remake, Kingdom Hearts Re:Chain of Memories, summoning Dumbo causes Sora to leave the battlefield for the duration of the technique.
