Les devinettes de Reinette (Ribbit's Riddles) is a clay animation series produced by the French production company Double Mètre Animation. In each 3-minute episode, the frog Reinette describes an animal that the viewer has to guess. As Reinette gives out the clues, the clay figure slowly takes the shape of the animal in question.
The episodes started to appear as inserts on Sesamstrasse, without the series intro, from season 36. When full Sesamstrasse episodes were viewable on the NDR website, this segment is cut from the episode.
