Mysticat

Leaves glowing pawprints everywhere and acts surprised. Its tail-flame flickers when lying about cookies.

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.

Mysticat hatches from the Magic Hollow egg. Every egg you open in that world can give you one, and the rarer the creature the longer that takes.
