Are rag dolls multicellular or unicellular?

Answer 1

Neither.

Rag dolls are not alive so it's as meaningless to ask if they are multicellular as it is to ask the same question about a brick or an iron nail.

If they are infested with bugs or molds, the infestation might me multi-cellular. The materials they are made from may have come a plant or animal that was multi-cellular - but the dolls are not.

Well - I suppose the "Rag Doll" of the Aerosmith song was multicellular...

The "ragdoll" (one word) is also a breed of cat. Cats, of course, are multicellular like humans.
