This thing turned out a lot cuter than I had thought it would.
The original design I had for this, kept the hood as a leaf, but then I thought, since it's gonna have an icy theme, why not a snowflake? So, now it has snowflake.
Despite it being a Bug/Ghost type, it only learns 1 ghost type move, prior to evolution, and that can only be done through TM. Rest assured, this Pokemon's evolutions do actually learn Ghost type moves.
