They like to eat lettuce. When we were in St John USVI a local told us to just place the lettuce on ground in front of us and once they finish it they beg for more. They raise their head , lick the sides of their mouth, bob the head like they're saying... well, where's the rest.

At Dvi Dutch Village one camped out near the pool. I went to the store bought a head of lettuce and every day he was there waiting for me. Once I gave him a generous piece he curled up under my lounge chair and slept.
