It starts with a real wombat
No animals are handled, disturbed, or interacted with directly. Each nugget is collected only after it has been naturally deposited and the wombat has moved on. That matters — both for the animals and for the authenticity of the story.
Then the joke gets serious craftsmanship behind it
Fresh material cannot simply be coated and called finished. Each piece must be stabilised, structurally protected, surface-prepared, and then taken through a slow metal-forming process that has taken extensive trial, refinement, and specialised handling to get right. The result looks playful on the outside, but the making of it is anything but casual.
