Every so often I run across links to this taxidermy mouse chess set available for $550 on Etsy.
The kicker, though, is the note in the item details that,
**** This item is made to order and will take at least 30 days to complete and dry before shipment can be processed.***
. . .
All specimens were acquired from a captive breeding facility that distributes frozen rodents for reptile feeding, so don’t feel sad if these little guys were not battling it out on the chess board they would be deep in the belly of a snake.
