Zuwa is a water based child form Spectrobe that evolves into Zuwaja and then into Zuwakrid. Zuwa can be excavated as a Zuwapod in its fossilized state.
Zuwa (child/first) has a strong likeness to that of a crab and robot. Its body is covered in blue, camouflage patterns. It has two pincers that it uses to crush anything, and a transparent storage compartment in its stomach for what seems to be mucus.
Zuwaja (adult/second) is a large crustacean with very robust features. Zuwaja is covered in a camo-like, blue pattern which allows it to hide under water. It has four legs, a long torso, and very large shoulder blades. Despite these menacing features, Zuwaja has very small claws. The most odd feature is the two spherical, transparent mucus containers on the back of its head.
Zuwakrid (evolved/third) resembles a blue scorpion-like creature covered in heavy bony plating. It's tail resembles the top half of a dragon's skull, and it uses this tail to slam down on enemies. It also has two small pinchers, but they are hard to see.
