Cane toad on top of cane (6)
I believe the answer is:
rattan
'cane toad' is the definition.
'rattan' can be an answer for 'cane' (I've seen this before). I'm not sure about the 'toad' bit.
'on top of cane' is the wordplay.
'on' indicates putting letters inside (as in clothing 'on' a person).
'top of' becomes 't' (I can't justify this - if you can you should believe this answer much more).
'cane' becomes 'ratan' (I've seen this before).
't' placed into 'ratan' is 'RATTAN'.
Can you help me to learn more?
(Other definitions for rattan that I've seen before include "Palm stems used to make furniture" , "Wickerwork material" , "Climbing palm; cane" , "Pliable palm stems used in weaving" , "Plant with stems used in wickerwork" .)
