Draghi suddenly stumbles in the middle of a big amorphous, whhooly, stinky, braying, multy headed and limbed monstrosity, and is too scared to know what to do about it... ( sheep flocks are scary! ).
I remember hearing on tv that zebra stripes are supposed to make the forms of the animal blend in to eahc other and make it hard for predators to pick out individuals. I imagine it could be applied to whool too.
Also, those vids of large dogs being scared to walk by a cat, make me laugh.
