Someone offered a level three pet crocodile for my non leveled pet spider monkey. I thought this was fair, because the spider monkey has been out of store for much longer, plus I looked at the worth and the spider monkey is worth more, but the other player said that I'd have to add something rare because the crocodile was leveled. I would have been willing to add a rim or something, but they said they wanted my galaxy wings. I thought that this would have been a huge loss, but they thought it was fair. I ended up canceling because I didn't want the crocodile anyway, but I'm wondering if it would have been fair to trade just the spider monkey, or if the galaxy wings and the spider money would have been fair.
