Craved last bit of roly-poly taken home (7)
I believe the answer is:
yearned
'craved' is the definition.
(I've seen this in another clue)
'last bit of roly-poly taken home' is the wordplay.
I cannot quite understand how this works, but
'bit' could be 'ear' (I have seen 'Bit of corn' mean 'ear' so perhaps 'bit' could also mean 'ear') and 'ear' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for yearned that I've seen before include "Pined" , "Desired strongly and persistently" , "Felt longing (for something)" , "Longed (for something)" , "Desired - longed (for)" .)
