Anyways, my idea was maybe you could release some kind of generic birthday pet or item?
Like, something that says Happy Birthday (but not to anyone in particular) on it that people could give to each other. Maybe something that you could buy from the store....?
If you could program it, maybe the pet could only be adopted through a trade (so you'd never actually own the pet you'd just trade it to someone else) and then once it arrived at the owner it couldn't be traded away.
Although that might make everything more complicated then it would be worth.
Might just be easier to treat it like a regular pet just make it a very common and let people adopt as many as they want. Or to make it a store item that they could buy for friends.
I still plan on getting my friends more interesting pets for their birthdays but I have occasionally thought it would be nice just to send some random pet to the people listed under the "birthdays" section on the forums and as most of the ones down there are going to be strangers it would be nice to have something a little more generic as I'm not sure I can get pets off their wishlists for every single random person I decide to wish a happy birthday.
Anyways, thanks for reading all this!
