I believe the answer is:
Here is my best explanation:
'foot?' is the definition.
'part of the elephants' is the wordplay.
'part of' says the answer is hidden in the clue.
'HEEL' is hidden in the letters of 'the elephants'.
(Other definitions for heel that I've seen before include "American rotter or shoe part", "Contemptible person", "Despicable type", "despicable person", "One of the crusty ends of a loaf", "Back part of the foot", "tip", "Scoundrel - list - shoe part", "Rotten type" and "Lean - back of foot".)
