So the Wizard gave me a pink sportbag. I opened it and got the gym token, but my question is... If I use it, will it increase my pet status with 1,34, 108 or whatever random points? And can I decide which will increase?

I used one once. It gave me +1 on a random stat if I'm not mistaken. Not really worth using it in my opinion.

Thanks, thats what I wanted to know. Its not very worth it for people who just started training their pets I suppose.
