I made this for my son's 27th. It's a long story, but it was the first I was able to make for him in 9 years (not jail, promise). Both tiers are square with the front corners cut off, then covered with the piping gel stream, chocolate rocks, buttercream icing and grass, fisherman and fish are fondant (fish are painted w/markers). I got inspired by another cake here (sorry I can't remember the caker). I can't sculpt to save my life. But I was able to do this. TFL.
