BOB from Monsters VS Aliens is prone to encasing people, accidentally or otherwise. In the case of the former, for instance, he hugs Susan's mother and traps her in his body; at Susan's insistence, he oozes her out. At the end of the film, however, he does this deliberately to Derek before oozing him and chewing him out for being a "selfish jerk".
On The Orville, Yaphit is a blob-like alien creature voiced by the late Norm Macdonald, who has a crush on the human medical chief and can feel every part of his body if it separates from him which happens once that Bortus, a fellow crewmember accidentally eats one because of a prank from a third party.
