Is Jellabies coming back?

The Jellabies are jelly-made children that live in the Jolly Jelly World, which is the magical land at the end of the rainbow, where their first job is to make rainbows. (for which they have a machine called the Jelliscope, a computer / teleporter / rainbow generator which is constantly monitoring weather conditions around the world) Although each Jellaby has its own vehicle to drive around in, their main use of travelling long distances around Jelly Land is on the "Jelly Train", a train that only consists of a cab (without any actual locomotive) and one passenger car.
