Gwappamon

Gawappamon is a Cyborg Digimon whose name either comes from a Gawappa (a type of kappa), or is the mix of three names for a Kappa: Gataro, Kawako, and Kappa itself. His data is mixed with that of a music player's, this is shown by the way you can put CDs on the plate of its head, and listen to music with the seaweed headphones.
