Digging deep in the mines he found an odd room with a pedestal in the middle illuminated by a strange light. On top a golden shimmering figurine of a cow.
Inspecting it closer he thought it must be worth some, though not knowing that the idol exchanges its shape with his.
And before he knew it it was done. Maybe setting the idol carefully back on the pedestal would help... oh... well gluing that back together with hoofs will take some time.
