My guess is the legs are the front and back of the box, which could be cut from the same or a sandwiched piece using a pattern. Use the pattern to cut the middle layered section to fit, but with the trunk, but without the legs. Glue the front together with the middle sections and do the bandsaw cuts, then glue the back piece on last. Sand to perfect the rounded shape and finish. At least that's one way to produce what is a very interesting band saw box. Nice work Bob, especially given the limited wood choices on the island.
The more I do, the less I accomplish.
