Touch European pond creature (7)
I believe the answer is:
tadpole
'pond creature' is the definition.
(I've seen this in another clue)
'touch european' is the wordplay.
'touch' becomes 'tad' (I've seen this before).
'european' becomes 'pole' (someone from Poland).
'tad'+'pole'='TADPOLE'
(Other definitions for tadpole that I've seen before include "Baby amphibian" , "Amphibian larva" , "Larval frog" , "Potential frog" , "Frog in formation" .)
