I made Jokie & Jet, the protaganist and his feathered sidekick from Carnaval Festival (1984) at Efteling. Carnaval Festival is Efteling's answer to Disney's It's a Small World. It even has a similar earworm of a tune during the whole ride. The backdrop is how the building looks from the outside. Before Vogel Rok opened you could see it next to the entrance of the ride, but now it is only viewable from the backlot or the streets. You can see it in this photo from the 80's. https://www.wonderlijkewcweb.org/attracties/carnaval_festival/artikel_fotos/entree1984_breed.jpg
I have added myself as a snowman entertainer. Carnaval Festival has a snowman called Pjotr. He is more prominent in the area during Winter Efteling.
