Our party has a weird question about the structural integrity of a Beholders eye. If a druid in starfish form was flung into a beholders eye by a fairly strong half orc, would the force be enough to pierce the surface of the eye?I'd give the beholder a Con save (8 + half-orc's Str mod and proficiency bonus)

Does passing within the cone of the Beholder’s eye cause the druid to shift back to their original form?
The beholder’s gaze stops spells from being cast and nullifies the effects of some magic items, but it wouldn’t turn back the druid into it’s original form, since that was a transformation effect that altered it’s body, it is neither an illusion nor a polymorph. As long as the druid was already a starfish before entering the cone, I wouldn’t doubt it’s capability to remain in such a state, tho the other way around may require further clarification.
