keep looking for open positions in the future at your store and keep in touch with the manager there and make sure they know that you really enjoyed working there....maybe you could try another toy store or working in the toy department at another store......
express your intrest and also see if anyone there would be willing to let you use them as a reference for future employment. Work environments are funny that way I have worked in ssome great environment that made me feel sad when I had to leave etc, but know there are most likely other places that will give you that same feeling. Keep working and getting your expierence up and what not wether or not you like the other place as much as you did at toys r us that way when a position opens up at toys r us, they will have hard time saying no and not keeping you on full time....
