Galleries should only apply to still images like screencaps, concept art, photographs, and promotional images, not moving pictures that last for a few seconds and have subtitles. The only moving pictures allowed on here are strictly videos. Gif images have been banned from this wikia ever since I joined, I wrote the ban myself and the Administrators agreed with it.
Upon seeing the edits you made to the Mouse Factory page, I think we should take the next step and start creating separate pages for each of the episodes, where we can list the clips shown and also which specific characters appeared in costume form in the live-action segments, including the opening sequences with the characters arriving for work and punching in.
Unfortunately, we would need to know every single episode and we don't. This show is pretty scarce on YouTube. For those reasons, I don't even know the exact order of every single cartoon featured on each show.
