Thomas and Friends Minis Fizz N Go Series! Each one comes with a block that bubbles and dissolves in water. When it is all gone it will reveal a surprise animal figure! This is so much fun for kiddos. My son loves these things. It is so much fun For kids to find out which animal they will get! It can also be a big disappointment when they start getting duplicates. It's a waste of money and I know, that my son would get upset when he got the same one. So I looked up all of the codes and provided a photo for proof. This one is Thomas and Panda, code # GGN41. I hope that this is helpful. Thanks for looking!
