This is probably pretty straight forward but I'd like some clerificarion about the Gourd Leshy's sneak attack.
Say there is a patch of the little beasties in gourd form, Adventures apoarch, then SURPISE! seed in the adventure's face, entangle insues, etc.
Roll initiative.
Now that combat has started can thr Leshy turn back into a pumpkin on it's next turn AND get a sneak attack off again once it reverts back into leshy form on a subsequent turn?
Or, now that the adventuressential are aware that it is a beastie, it cant catch them flat footed again, even though they won't know when it will try to attack again?
The latter. If there's enough stuff to hide in, it could try a Stealth check at -20 for sniping following the attack, but good luck.
Note that change shape is a standard action, so the PCs might see them before they have a chance to attack (another standard action).
