Fish found in wheelbarrows (3)
I believe the answer is:
eel
'fish' is the definition.
(eel is a type of fish)
'in wheelbarrows' is the wordplay.
'in' indicates the answer is hidden within the clue.
'EEL' can be found hidden inside 'wheelbarrows'.
'found' is the link.
(Other definitions for eel that I've seen before include "Elongated fish" , "Long thin fish" , "Teleost fish" , "Slippery character" , "Snaky fish" .)
