Generic Children's Television Jump

From the introduction: Hello there, Jumper. Now this world may seem familiar to you, but I assure you, your adventures are not yet over. In this world, things are much simpler and far more innocent. It is a world of imagination and wonder, where children are allowed to be children, and everything seems brighter. It’s not a perfect world, and sometimes things can go wrong despite your best efforts, but I can safely say that you have nothing to fear from this place.
