If you are a kid, PLEASE ask your parents permission first before buying. 

After buying :
1. Please send me your username so I can add you 
2. Please accept my request after I add you 
3. Please join me in the game but please wait for me to teleport to you so that I'm ready with your pet(s) and not with other buyers.
4. After the transfer, I might remove you from my friend's list. Nothing personal, this is just for ease of operation, as I might get confused and give the pets to the wrong person.
