Kale's heart is Halley's comet. she travels with it to various locations, but she cannot be separated from it for too long. because of this, she usually leaves her friends behind for good, and often forgets them.

she is made of rock, ice, and space dust. her tusks help her to eat rocks, which is her main source of energy. she can levitate and fly through the air at will, which leaves her legs mostly useless.
