Turkey leg Bob demolished? Right! (7)
I believe the answer is:
gobbler
'turkey' is the definition.
(gobbler is a kind of turkey)
'leg bob demolished? right' is the wordplay.
'demolished?' is an anagram indicator.
'right' becomes 'r' (common abbreviation).
'leg'+'bob'='legbob'
'legbob' is an anagram of 'gobble'.
'gobble'+'r'='GOBBLER'
(Other definitions for gobbler that I've seen before include "Male turkey" , "One quickly eating - turkey" .)
