Popplers

Popplers are undeveloped Omicronian young. They are born into large pits on a nursing planet (type M) the Omicronians to not take care of their undeveloped young but they do have "Nanny-Cams" positioned around the planet to keep an eye on things. Because they are undeveloped they have an irresistible taste to humans and many alien species. Popplers were first discovered by Planet Express employees Fry, Bender and Leela. Fry discovered the pits of Popplers, and Leela defined them as edible. They were then proved to be addictive so they filled the Planet Express Ship with them and brought them to Earth then sold them to Fishy Joe's.

However, when their true origin were revealed to the humans, the immediately went out of business. Perhaps also due to the threats by the Omicronians.

Trivia

 * Popplers originally were going to be called "Tasteticles" but it sounded to much like "Testsicles". When informed that the only two names not trademarked were "Popplers" and "Zitzlers," they agreed on Popplers.
 * Fishy Joe's sold Popplers using this jingle: Pop a Poppler in your mouth when you eat at Fishy Joe's / Where they came from is a mystery, what they're made of no one knows / You can pick 'em, you can lick 'em, you can chew 'em, you can stick 'em / If you promise not to sue us you can shove one up your nose!
