Kodomo Challenge Pocket Kodomo Challenge Kazu Penguin This is a toy for learning numbers 1 through 5. You play by putting the penguins on sleds and sliding them. The penguins won't ride the sleds properly unless you put them on the sled with the same number as the penguin's belly. I didn't play with it much, but it has some scratches because it was stored with other toys. Type: Number Character: Shimajiro
