Teddy Tank "Charming Penguin"

I bought this for my penguin loving niece for Christmas. It is so cute and will be a wonderful keepsake holder. I don't think I would put a live fish in it as advertised, seems like it would be difficult to keep the tank clean. Although you could get a little plastic floaty fish and put it in the tank. I thought about filling it up with penguin crackers and letting her use it as a snack container. A fun toy for the 4 plus scene, including adults.
