That sounds like a lovely little machine—rust, cranks, a bell, and the gentle clatter of leaves. If you’re looking for something oddly shaped, maybe a maple leaf with all its pointed edges would fit nicely, or a feather leaf that’s almost like a miniature quill. A pine needle cluster could add a different texture, and a heart‑shaped leaf would make it feel a bit more whimsical. Pick one that sings to you, and the vending machine of wonder will be ready to whisper its secret names.
