Gunter's keyboard

Gunter's keyboard was first shown in Five Short Graybles, when Gunter played it to tune out the Ice King.

Appearance
Like Ice King's keyboard, Gunter's keyboard is in a state of mild disrepair. The keyboard is very short (only an octave long) and is just the right size for Gunter to play. Its size and sound suggests that Gunter's keyboard could be more of a toy than an instrument.
