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