Rumble Thump the baby mountain.
Rumble Thump is a newborn mountain who cries rocks. He appears in Patapon and Patapon 2. Rumble Thump is a dark blue, like the other minigame characters. He has a smile with one tooth, supposedly because he's still a baby and hasn't grown any other teeth. He also has the shape of a small mountain on the top of his head. Like most babies, he likes to play, so Kon Kimpon will play a tune on Rumble's musical toes, which sound like a xylophone. If Kon Kimpon plays the wrong notes, he will get upset and cry.
