The whole lot is transplanted into a cool bed (8)
I believe the answer is:
caboodle
'the whole lot' is the definition.
(I've seen this in another clue)
'transplanted into a cool bed' is the wordplay.
'a cool bed' anagrams to 'CABOODLE'.
However, I am not sure how this is indicated.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for caboodle that I've seen before include "The whole kit and ..., the lot" , "Group" , "Crowd, collection" , ""The whole ___" - everything" .)
