I am SO changing the savage monkey attack in the beginning of Bullywug's Gambit. The PCs will see a few dead savage monkey corpses, and one or two writhing in pain, all of them mauled half to death and punched full of tiny holes. What's more, their flesh seems to be bulging and squirming in a noisy, disgusting manner. What's even more disturbing are the faintly noticeable clots of webbing anchoring the moneky's limbs to the ground, apparent after bringing some light near the tortured creatures...
... and that's when the savage webbirds burst forth from their monkey hosts! The mature newborns immediatly screech and writhe in their own unique, mutated ways and take wing to begin their nightmarish work, starting with the PCs. This is only the first wave, of course...
Seriously, the webbird is like the coolest thing ever.
