Quick question here. Snatch specifically states if a creature grappled is three size categories smaller than the grappler can automatically squeeze and apply bite or claw damage.
Does this ability only allow the Hydra to grapple small opponents on a successful bite or claw? Or could the Hydra grapple any opponent on a successful attack but be restricted to squeezing small creatures (assuming huge hydra).
Also, if the hydra can grapple (grab) with its bite, can it maintain a grapple with each mouth on separate opponents without taking a -20 to the CMD or do all of its heads have to grapple a single target? By RAW I think it has to but Hydra's are a little unique.
