Query: A must-have!

I bought this toy for my then-16-month old son who loves to play with magnets on the fridge. This set comes with five animals in two pieces, head and tail, per animal. What I liked about this toy is that it reinforces when a match has been made, BUT if a child isn't developmentally able to do that yet, it makes up a name for the animal the child has "created" by mismatching the tail and head (for example, a "sheep-cow"). I liked that it saw a mismatch as silly rather than wrong... good for very little ones who have low frustration levels. This is a quality toy, with clear sound and easy-to-grasp pieces... I'm a picky person when it comes to toys, and I highly recommend this one!
