We spent many a hour with our weird dancing little edutainment friend me-mo-mo. I mostly recall playing the block pushing puzzle and music mode, but I perused the manual and was reminded how many games there are--matching and Simon and word games and math games abound
The most important feature though, is how it would dance
The little legs would wobble, and the screen would display its happy eyes and it'd do happy dance when it woke up or you completed a level (and I think there was just a oops all dances mode?); if you didn't suction cup it or give it a stable enough stance, it would dance itself over.
