Squirrel
From Record Of Fantasy Adventure Venture
(a.k.a. OH GOD SQUIRRELS!!!!!)
Small, bushy tailed and cute, the common Squirrel may be the most dangerous creature listed in the Bestiary. Their quiet cunning is only matched by the ferocity of their swarming attacks. The best way to handle such creatures is to burn down the forest with them in it. Unless, you travel with Druids or Rangers in which case your only sane option is to run.
Seriously, these things are dangerous.
