Weird one tucked into end bits found on little piggies? (8)
I believe the answer is:
toenails
'found on little piggies?' is the definition.
(little piggies are toes)
'weird one tucked into end bits' is the wordplay.
'weird' is an anagram indicator.
'tucked into' means one lot of letters goes inside another.
'end bits' becomes 'tails'.
'one' with letters rearranged gives 'oen'.
'oen' placed inside 'tails' is 'TOENAILS'.
(Other definitions for toenails that I've seen before include "types of digital hardware" , "Extremities" .)
