Octopus Under the Sea Cake

The theme was just "ocean" so I narrowed it down and went with an octopus as the main attraction . . . we were in Seaside recently and the octopus on display at the aquarium was fascinating, so naturally I gravitated toward that. :~) The bottom tier is a two layer chocolate cake covered in marbled buttercream. The middle is yellow cake, as is the head of the octopus, who is covered in marshmallow fondant. Couldn't resist turning the extra batter into the family of Octopi surrounding the cake!
