Whodunnit?

Last week, I bought a lovely fresh Costa Rican pineapple. I left it outside overnight on the patio table as I did not want to attract fruit flies into the house.

The next morning, this is all that was left of it:

 Pineapple juice and pieces all over the place! Had to hose everything down so ants wouldn't be attracted.

There were chunks of pineapple peel all over the place. I found the green leaf top under the orange tree.
I did the same thing the following week and the same thing happened. Our neighbours have seen a opposum at their house so maybe that is who our thief is. One of these nights, I'm going to sit up with my camera and see who the thief is.
