99 Puppies

The 101 Dalmatians make an appearance as a whole family as well as a side quest in Kingdom Hearts, where Sora finds and rescues their puppies (from chests). Despite being listed as 101 Dalmatians, there are only 99 puppies to be found; this is because their parents, Pongo and Perdita, are excluded.
