Toy with ape’s wobbly nose (10)
I believe the answer is:
peashooter
'toy' is the definition.
'with ape's wobbly nose' is the wordplay.
'with' means one lot of letters go next to another.
'wobbly' is an anagram indicator.
'nose' becomes 'hooter' (hooter is a kind of nose**).
'apes' is an anagram of 'peas'.
'peas'+'hooter' is 'PEASHOOTER'.
(Other definitions for peashooter that I've seen before include "Toy weapon" , "Child's "gun"" , "child's toy" , "Primitive weapon" .)
