I share my birthday with Pierce, the jock eagle villager. I've never had him on my island, and I don't think I've made a HHP vacation home for him, but I could have sworn I saw him on my HHP island yesterday, so maybe I did?
Cesar, technically I'm scared of monkeys, so sharing a birthday with a gorilla isn't cool.
But!! For some reason everyone on my family thinks my bday is on septermber 9th (three days later) and always congrats me that day. So I kind of end up celebrating my bday on the 9th usually instead of on the 6th, which makes Pinky my (lowkey) bday twin too
