Sparkly reindeer-dung necklaces are going on sale at an Illinois zoo that hopes to attract the same holiday shoppers who swept up its dung Christmas ornaments last year.
The limited-edition Magical Reindeer Gem necklaces will debut on Friday at the Miller Park Zoo in Bloomington.
The $US15 ($A16.43) pendant necklaces contain dried, sterilized reindeer droppings - sprayed with glitter - on a beaded chain. They'll be available at the zoo's gift shop, or by mail for $US20 ($A21.91).
The ornaments are back, and 450 have already sold this season. About 1,500 are still available for $US7.50 ($A8.21), or $US10 ($A10.95) by mail.
Miller Park Zoological Society spokeswoman Susie Ohley admits it's a bit silly but estimates the zoo could make $US16,500 ($A18,072). The zoo lost $US200,000 ($A219,058) under city budget cuts this year.
