Review on Discover the Whimsical World of Hasbro E4458 Lost Kitties Multipack by Nick Reddy

My two boys (10 and 5 years old) love these Lost Kitties. The toys inside are very cute and collectible. My only complaint (and that of my 10 year old) is that the toys are surrounded by putty or plasticine-like material. The kittens are wrapped in polyethylene, so getting them out is pretty easy. But the "cat toys" included in some of them are very difficult to get out and clean because they are buried in putty. I don't understand the meaning of the mud either. My children hold no putty. It doesn't come in a container to keep it from drying out, so it's always thrown away with the packaging (which I find very wasteful).
