The three minute segments focus on the simple adventures of the three main Plonsters: Plif, Plops and Plummy. They have the ability to morph into any animal, vehicle, or other object. The characters have also been merchandised, in the form of plastic figurines, and their skits have appeared on Sesamstrasse videos. The series is produced by Anima Studio Hamburg, with more recent segments co-produced with the Danish firm Egmont Imagination. Anima produced other clay animated segments for Sesamstrasse, featuring such characters as the Plastinots and Bronny the Bear.
