Lobster found on a pencil (6)
I believe the answer is:
crayon
'a pencil' is the definition.
(I've seen this before)
'lobster found on' is the wordplay.
'lobster' becomes 'cray' (I am not sure about this - if you are sure you should believe this answer much more).
'found' says to put letters next to each other.
'cray'+'on'='CRAYON'
Can you help me to learn more?
(Other definitions for crayon that I've seen before include "Cyrano (anag)" , "drawer" , "Wax colouring stick" , "Pencil of chalk or wax" , "Writer" .)
