He's out of shape - droopy! (5)
I believe the answer is:
pedro
'he's' is the definition.
'out of shape droopy' is the wordplay.
'out of' indicates the answer is hidden within the clue.
'PEDRO' is hidden within 'shape droopy'.
(Other definitions for pedro that I've seen before include "Common Spanish name" , "Mexican perhaps" , "Five" , "Spanish for Peter" , "Spaniard" .)
