Federal customs agents pooh-poohed the plans of an Iowa woman who wanted to make jewelry from giraffe feces she picked up on a trip to Kenya and brought back to the U.S. in her luggage.

The woman declared the small box of feces when she was selected to have her belongings inspected upon arriving at the Minneapolis-Saint Paul Airport on Sept. 29, according to U.S. Customs and Border Protection.

The woman, who was not identified, told officials she planned to use the waste to make a necklace, as she had done in the past with moose poop.
