My parents went on a Caribbean cruise last week and brought back seeds from three different mystery plants. They don't remember what the plants/trees/bushes looked like.

I took a picture with a ruler for scale. The second and third seeds were both inside of small fruits. I have a hunch that the second one might be from a fiddle leaf fig, but I don't know that for sure. The other two are complete mysteries.

If anyone has any idea what these might be, I would appreciate the help.
