I don't think nicknames are a big deal, but seeing as my name begins with 'I', I get names like 'I-Robot' which I hate. I'm quite girly, I prefer cuter nicknames. I wouldn't mind being called cookie at all!
well my character name is hobbes and the animals call me H-star and scout. i like scout but i hate H-star so wait until a animal asks you what nickname you want and put your name or the nickname you want
