Although they 'normally lack chaos features' (Gloranthan Bestiary), I've
always assumed krashtkids to be chaotic or at least chaos-tainted, hence
you'd expect a wide variation in appearance. The Bestiary illustration has
six symmetrical limbs or 'digging claws'. It notes that little is known of
them - so there may well be entire 'tribes' or 'subspecies' of asymmetrical
pratzim-spitting lop-sided kashtkids, or mottled pink and grey spider-rabbit
krashtkids who attack by singing a dub version of 'Like a Virgin'. (EC vs
Marketing 15w), in addition to Ocron Everseer's reported symmetrical,
crab-like krashtkids.
This will doubtless be an advantage in 3D modelling, when we come across
those infuriating 'don't fit/don't scan/stoopid software' moments.
Chaos is chaos. Mystery is mystery, at least until the fundamentalists and
literalists get hold of it. With krashtkids, you should expect the
unexpected.
Yesnomaybe?
