Cindersnap

Its jaws crackle like burning logs, startling itself every time. Stomps with volcanic bravado despite the trembling.

Forms

The same creature at each step of its evolution. A form is crafted from the one before it, so the ladder is climbed in order.

This creature has a shiny version at every step of the ladder. Shiny is its own roll, so it can turn up on a plain form or on a fully evolved one.

Cindersnap hatches from the Molten Depths egg. Every egg you open in that world can give you one, and the rarer the creature the longer that takes.
