Head missing from toy that's stuffed in Whirlpool (4)
I believe the answer is:
eddy
'whirlpool' is the definition.
(an eddy is a small whirlpool)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for eddy that I've seen before include "Whirl (in fluid)" , "Little whirlpool" , "Ripple" , "Turner at sea" , "Founder of Christian Science, d. 1910" .)
