99 Puppies

The 99 Puppies make an appearance as a side quest in Kingdom Hearts, in which Sora is given the task of finding them in various worlds. It is not a requirement to find all of the puppies in Kingdom Hearts, but doing so yields various rewards, which includes unlocking the secret ending on normal difficulty, an Aero upgrade, as well as a full Gummi Block collection.

Kingdom Hearts
The puppies originally resided in a currently unnamed world in the Kingdom Hearts universe, raised by two adult dalmatians, Pongo and Perdita. At some point, the dalmatians' world was destroyed and the puppies were separated from their parents. During the chaos of their world's destruction, the puppies were somehow bundled into groups of three, and were separated across the various worlds of the Kingdom Hearts universe.

During his journey, Sora finds and frees each group of puppies, sending them to Traverse Town, where Pongo and Perdita had found a temporary home.

Puppies can be found on scratch cards in the Avatar Menu. D-Firaga is awarded after collecting all 99 puppies.

Appearance
The most notable thing about these dalmatians is that they wear different colored collars to signify their genders; females wear blue collars, whereas the males' collars are red.

Puppy No. 5 is actually Patch (パッチ), No. 6 is Rolly (ローリー), and No. 12 is Lucky (ラッキー) (the puppy who sits in front of the television set). Puppy No. 13 is Pepper (ペッパー), No. 23 is Penny (ペニー), and No. 69 is Freckles (フレックルス).

Personality
As there are ninety-nine of them, the puppies have varied personalities. Their common traits include hyperactive, child-like behavior. They all enjoy watching television, but are all very well-disciplined by their parents. In one of the rooms in the Dalmatian's House, one puppy will happily follow Sora through the room, proving they seem to like Sora.

Origin
The 99 Puppies are based on their appearance in Walt Disney's 1961 film One Hundred and One Dalmatians, which was in turn based on the 1956 book The Hundred and One Dalmatians by Dodie Smith. The puppies' main characteristics, along with some of their names, remained for the transition from book to film. However, the film added two dalmatian pups to the book's original count of ninety-seven; in the original book, two additional adult dalmatians round off the total one-hundred-and-one, as the four adults were merged into Pongo and Perdita for the film.
