March 25th! Although Whimsicott is the April pokemon, the human Aries sign says March 25th is allowed, so. Whimsicott's horns look like mine, and those of my lusus.

Anyway! The list is, from January to December: Sawsbuck, Simipour, Alomomola, Whimsicott, Bouffalant, Klink, Crustle, Braviary, Gothorita, Lampent, Scolipede, and Fraxure!
