Sharp pegs or otherwise for small jumper (11)
I believe the answer is:
grasshopper
'small jumper' is the definition.
(I've seen this before)
'sharp pegs or otherwise' is the wordplay.
'otherwise' indicates anagramming the letters.
'sharp'+'pegs'+'or'='sharppegsor'
'sharppegsor' anagrammed gives 'GRASSHOPPER'.
'for' is the link.
(Other definitions for grasshopper that I've seen before include "Insect (that won't stay still for long?)" , "Chirping insect" , "small jumper" , "Type of cricket" , "six-footer with extra powerful legs" .)
