Quilled chameleon

The Quilled Chameleon is a chimeric reptile found in the densely forested areas of the Earth Kingdom. Being cellularly pigmented, Quilled Chameleons are able to change color in order to effectively blend into their surroundings.

Anatomy
The build of the Quilled Chameleon is almost identical to that of its real life counterpart, though certain parts of its body, particularly the head and the front legs, resemble the body structure of other fauna. The Quilled Chameleon has a peaked trilateral head similar to prehistoric pterodactyls. Feather-like quills extend from its front legs, which possibly allow the animal to glide through the air for short distances. These quills may also be structural adaptations meant to aid the creature in battle, or specialized parts used in daily life functions. The only Quilled Chameleon seen in the series had a distinct green coloration. It is unknown whether or not this is the standard basis color of the species, though a particular creature's exposure to a vastly different environment may alter its natural color patterns.

Connection
The Quilled Chameleon resembles the real life chameleon, as well as exhibits physical characteristics present in the now extinct pterodactyl. It's body is embedded with feather-like quills, which suggests that the creature is either connected to a particular bird or to the North American Porcupine.
