He wasn't too difficult to make, but I don't think I'd like to make a lot of them at once. It would be WAY too time consuming.
First, I piped the chocolate design on his back. Then I filled in the spaces with dark green piping gel (it can get a bit runny so be careful). Next, I piped on a head, tail and four legs around th eedge of the cupcake. Be sure the icing you use is stiff. The icing we had was store-bought and kept wanting to slide down. Finally, I piped the whites for the turtles eyes and dabbed chocolate dots on them.
He's a bit messy, but kinda cute, too. The kids wanted to eat him before I could take a picture.
