Midbus has not appeared in A Day With Bowser Jr yet, but dannywaving has stated on DeviantArt that he might add Midbus to his series, with Midbus possibly being an auditionable character for the next episode of A Day With Bowser Jr. dannywaving has also stated that Midbus is the hardest character for him to model due to the fact that the model for Midbus is too complex for him to make. Despite his, dannywaving might be trying to make a model of him for the series, though.
