Well it is possible to delete a group ^^ if that helps lol
And one thing that I can say is that...be random. Don't worry about the RPs if that isn't your thing. Make some random character and go to like...Bonfire in the middle of the day and just do whatever, make a funny group like a gummy bear group, join a random conversation, start a danceline, anything! My best memories on this game was when I did that kind of stuff. People around you love it, you'll have fun, and you'll be falling out of your seat laughing sometimes. Honestly, I don't go online much anymore, I'm becoming a forum person until I can get a break from life lol. And I am sure that a bird group will start, I have seen plenty. Just gotta get creative. As for Pokemon, though I am not skilled in that knowledge, just start asking around, make a char based off of it, if someone knows I am sure they will comment. :3 hope this helped!
