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.
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.
Kingdom Hearts: Chain of Memories
Dumbo appears as a summon card after clearing Monstro's Room of Truth. When his card is used, Dumbo appears in battle and douses enemies to deal ice damage. Stocking multiple Dumbo cards create the Splash Lv2 and Splash Lv3 sleights, which increase the effectiveness of the attack and allows the player to control its aim.
Dumbo is the main protagonist of the 1941 Disney animated film of the same name.
In the film, Dumbo is originally named "Jumbo Jr." by his mother, Mrs. Jumbo, but ridiculed by everyone for his abnormally big ears. After his mother is locked away after attacking some boys who were bullying her son, Dumbo is befriended by Timothy Mouse, who becomes determined to make Dumbo happy again after the other elephants abandon him. With Timothy's help, Dumbo eventually discovers his ability to fly with his ears and becomes a superstar at the circus. He is reunited with his mother at the end after parting ways with Timothy.
