'the horny fellow' is the definition.
'devil' can be an answer for 'fellow' (thesaurus). I'm not sure about the 'the horny' bit.

'dutch wants depravity' is the wordplay.
'dutch' becomes 'd' (common abbreviation).
'wants' says to put letters next to each other.
'depravity' becomes 'evil' (I've seen this before).
'd'+'evil'='DEVIL'
