Grapdelites

From Muppet Wiki

Grapdelites are adorable and delicious mammals. In fact, they're so delicious, that almost all of them have been eaten. In Dinosaur culture, grapdelites are the traditional gift for a 20th wedding anniversary.

Earl Sinclair buys a pair of grapdelites for his anniversary in a second season Dinosaurs episode, "Endangered Species" -- and it turns out that those are the last two grapdelites left on the Earth.

While they're waiting to be slaughtered and cooked, the intelligent and thoughtful animals make friends with Robbie Sinclair, teaching him about the value of protecting endangered species.

The Grapdelite puppets were reused in "When Food Goes Bad" and "Nature Calls".
