Meet Mo, the Fizmo, who first appears in Striving for the stars, Book 1 of the Kelras chronicles.
Mo is an AI drone, who is skinned with a cosmetic skin designed to mimic the appearance of a creature called a Fizmo.
This particular Fizmo skin was custom made for Cadet Aristeia Kelras.
The Fizmo are small creatures native to the planet Marlu. They bounce through the forests, using their tails as a spring. These creatures are frugivores, using their tails to pluck fruits from nearby trees.
