Young animated character in the Stones (7)
I believe the answer is:
pebbles
'stones' is the definition.
(pebble is a kind of stone)
'young animated character' is the wordplay.
I cannot really see how this works, but
'character' could be 'pe' (pe is a kind of letter of the alphabet) and 'pe' is present in the answer.
This explanation may well be incorrect...
'in the' is the link.
Can you help me to learn more?
(Other definitions for pebbles that I've seen before include "Small, smooth, rounded rocks" , "Small round stones, as on beach" , "Small rounded stones" .)
