Corrected entry: When Riker is dragged into the pool of goo, his head reappears for just a moment, then is pulled back into the pool. Note that his mouth is open and fills with goo, but his mouth is above the surface. Obviously this is a mask that is pulled under.

Correction: The pool of goo is a living, shape shifting entity called Armus. If Armus wanted to only partially fill Riker's mouth with some of himself, it surely would have been in his power.
