beret (89a) + tree 木 (10a) = grain 禾

Notice how “beret” differs from “label”.

The meaning of “grain” embraces all cereal plants, including rice.

The beret (that they’d been using as a frisbee) is now stuck in a tree and they won’t be able to retrieve it without trampling the grain growing around the tree. (Who’s going to be the one to ask the farmer if they can get it?) / [No pronunciation needed]
