Forest creature can hide bananas (7)
I believe the answer is:
echidna
'forest creature' is the definition.
'echidna' can be an answer for 'creature' (echidna is a kind of creature). I'm not certain of the 'forest' bit.
'can hide bananas' is the wordplay.
'bananas' indicates anagramming the letters (informal term for mad).
'can'+'hide'='canhide'
'canhide' with letters rearranged gives 'ECHIDNA'.
Can you help me to learn more?
(Other definitions for echidna that I've seen before include "This insectivore" , "Toothless type" , "Little animal" , "Insectivorous mammal" , "One preying on the workers" .)
