Butterfly

Out for a peaceful walk in the park. When all of a sudden... WHAM! THUD!! Krow gets knock down by his faithful(?) companion Cerberus or Cerbi for short. And one of Cerbi's favorite pass times when at the park is chasing butterflies. Until he over does it and runs over Krow.
As for the name 'Cerberus' it is just a name since he is a demon hound. And even though he looks like that he does not have 3 heads.
(Just saying 'cause that would be weird...) (>~<)
