Things are bound to get a little messy in this mud-filled game featuring the silly puff ball Cuz-Cuz. Kids click on mud piles that have the short O sound in them, sending Cuz-Cuz straight into the mud where he'll get all dirty in the name of phonics-building fun. Identifying vowel sounds in words is an essential part of early reading, and this game is a great way for kids to get the practice they need.
