树种

树 = 对 + 木 : Sheldon Shrimp cultivates a Christmas tree in the space station's bathroom. He is very happy that he found the right tree, just the one he imagined, and—in his mind—marks of the tree he imagined with a big green check mark.

种 = 中 + 禾 : Inside of the engine, Julian Giant Squid prepares his cereals from the very beginning. He grows and picks up seeds, dries them on a dart board, and puts the dried seeds into his cereals.
