Zymod

Zymods were a type of color-changing reptile native to the jungle moon Ajan Kloss. They had poisonous tongues and webbed feet that let them climb almost anything. The Resistance base established on Ajan Kloss in 34 ABY suffered a small infestation of zymods, and in 35 ABY, the Jedi-in-training Rey had to dodge the flick of one's tongue while on the base's training course.
