Doudah released a series of "make-your-own" figures of characters from Sesamstraat, the Dutch co-production of Sesame Street, in 2006.
Each set contained different colored Magic Sculpting Putty and detailed instructions on how to sculpt them into "your own Sesamstraat heroes". After mixing the colors and building the characters by rolling the clay into basic round shapes, it takes less than a day for the clay to dry into a kind of lightweight plasticine.
The series consisted of Pino, Ieniemienie, Bert and Ernie.
