DanceDanceRevolution 5thMIX (Arcade / 2001) - Gameplay 

Here we have DanceDanceRevolution 5thMIX - and you know what that means. BABY-LON. Let's see what RemyWiki has to say about BABY-LON:
"BABY-LON is a baby, but when he puts on the magic earmuffs he got from his adventurer father, he becomes a super baby with killer dance moves. When he takes them off, though, he's just a regular baby."
Brilliant.
