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 missing, supposedly because he is still a baby and it hasn't grown in. 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 cry.
