Kingdom Hearts II
Beauty and the Beast (1991)

''Mrs. Potts's little boy. Chip became a teacup when an enchantress put a spell on the castle.''

His missing front tooth became a little chip on the rim of this teacup.

Kingdom Hearts II
Beast locked his servants in the dungeons after Xaldin came and tried to turn him into a Heartless. When Sora and the others came, they freed the servants and helped them save Beast from turning into a Heartless. Lumiere and the others showed them a short cut to the Beast's room.

Upon Sora's return, the Beast and Belle were having a party when Xaldin reappeared and took the Beast's enchanted rose. All that Chip could do was to observe the victory.

Trivia

 * Haley Joel Osment (the voice of Sora) was the voice of Chip in Beauty & the Beast: The Enchanted Christmas.
