Doremifasolati Do ドレミファソラティ・ド
Doremifasolati Do is described as a Rock Animal with a caterpillar-like body. Its face vaguely resembles that of a dog or bear with the tongue constantly sticking out. Its head sports several grooves, having deeper grooves extending from its eye-sockets. The rest of its torso is made up of several flat rectangular stones, adorned with designs resembling human arms. These flat stones provide excellent defense from attacks and can be shifted rapidly like tank treads to mobilize underground.
On each side of Doremifasolati Do's torso are two stones that are topped with spinning rock-like human hands. Doremifasolati Do also has a tail in the shape of humanoid legs that is made up of the aforementioned stones, allowing it to stand when above ground. Its torso lacks any internal organs, instead being hollow. This functions as a makeshift cockpit, allowing a person to hide within its body like a shell.
