Plinfa

Diamond +2: Because it is very proud, it hates accepting food from people. Its thick down guards it from cold.

Pearl: It lives along shores in northern countries. A skilled swimmer, it dives for over 10 minutes to hunt.

Platinum +4: A poor walker, it often falls down. However, its strong pride makes it puff up its chest without a care.

HeartGold +3: It doesn’t like to be taken care of. It’s difficult to bond with since it won’t listen to its Trainer.

Legends: Arceus: Prefers cold climes and appears along coasts. It's an adorable little thing—as cute as any child—but it's also prideful, unwilling to accept handouts from people.
