Hexy, for various reasons, had to be disguised.
He got invited to his first party, but the invite said "please bring other halves, children or pet tortoises" (again, something about my friends could be derived from this invite).
Necessarily, Hexy needed a disguise.
One plushie turtle, velcro patches and some green flannels later and you have yourself a passable mutant tortoise.
I figure that this now is Hexy halfway qualified as a Transformer; robots in disguise after all! (too sad?)
I have had it suggested that the next costume that Hexy should get is something based on this, but part of me thinks that the sci-fi cred that I'll get here will be offset by the huge amount of creepy...
