WMG / Marvin the Tap-Dancing Horse

The series is set in another part of Nowhere Land

Since it was made by the same people who made Maggie and the Ferocious Beast it makes sense. Given that the animals have the same intelligence as the humans and that Nowhere Land is pretty large it’s totally possible the carnival travels throughout a part of Nowhere Land that Maggie, Hamilton, and The Beast have yet to travel to.
