I believe I share a birthday with Tammi the monkey! (In New Leaf anyway. Beforehand it was April 1st but they moved it to April 2nd because April 1st in NL has an event that takes place within villagers' houses.)
Jay the jock penguin on July 17th. I haven't seen him before (New Leaf is my first AC game) so I looked him up and he looks pretty cute and has a cool looking music room. For these two reasons alone I feel tempted to get his Amiibo card and have him move in to my town.
