One of many puppet characters created by Jim Henson (6)

I believe the answer is:

muppet

(Other definitions for muppet that I've seen before include "Weak person (informal)" , "Kermit or Miss Piggy, say" , "Jim Henson puppet" , "Idiot" , "Fool - Jim Henson creation" .)

I've seen this clue in The Guardian.
