Funktionide is a robotic blob made of electroactive polymers which provide the movement; it is an emotional robot that can cure lonely, disconnected people by providing them with the loving, non-judgemental contact that everyone needs.
See if you still believe all that stuff after looking at the video below.

I really have to disagree with Funktionide creator Stefan Ulrich; a blob that crawls into bed with you is really not going to make me relax.
However, I gamely took my best shot at trying to think of a blob that was presented in a positive light in science fiction, which as a genre seems to mostly warn us about the danger posed by blobs.
Anyway, the only positively presented blob that I can recall is the Pinkness from Clifford Simak's excellent 1961 novel Time is the Simplest Thing. It is described as a... well, room-sized blob that is able to communicate telepathically with human beings.
Far away he saw the life - the thing that sprawled limply on the floor... it was pink: an exciting pink... the kind of pink the little girl next door might wear at her seventh birthday party.
It was aware of him. And it was not afraid.
It was a fairly massive thing, twelve feet high or so in the middle of it, and it sprawled across an area twenty feet or more in diameter... It was just a lump.
Then he sensed the flutter... the flutter of the being that sprawled pinkly on the floor - the flutter of a thought half-formed, the beginning of communication...
