PattyO about 7 years ago I can't be sure, but to me this looks like 2 ditto having sex with each other.
BakaBlue about 7 years ago It could just be one ditto, considering the fact that ditto doesn't breed with its own species (despite its lack of hesitation to pursue almost everything else that moves).
Disclord over 6 years ago Ditto is just a breeding machine. It never stops. Right now he is just passing the time while you decide on what pokemon to drop in the day care next.
