Kraken eats men! So scary, right? (3,7)
I believe the answer is:
sea monster
'kraken' is the definition.
(kraken is a type of sea monster)
'eats men so scary right?' is the wordplay.
'scary' is an anagram indicator (a scary or strange order of the letters).
'right?' becomes 'R' (common abbreviation).
'eats'+'men'+'so'='eatsmenso'
'eatsmenso' anagrammed gives 'seamonste'.
'seamonste'+'r'='SEA-MONSTER'
(Other definitions for sea monster that I've seen before include "A danger to mariners" , "fabulous swimmer" , "dangerous creature in the main" .)
