You may remember his creations back from the mid 2000's but thankfully, I have founded some of his stages if you feel delighted to download them!Download Link:https://sites.google.com/site/wlanmanslab/hosted-m-u-g-e-n-stuff
Thank you. I was looking for some of these stages for a while now.And those Colonel Sanders and Santa sprites edited from Peter Griffin are really something.
UPDATE (16/08/2018): I have added Halo War, Halo Snow level, Fat Albert's Junkyard and Puente Negro from my hosted section if you may download these stages!
It's a good question, I travelled around the web history with suing Web Archive how I can found some of old stages made by Mugen Toons. I tried to download more of his lost materials, especially from what I have seen are the Television stage, the Incredibles, Teletubbies, Timmy's Room, Pinata Bonus, Cheerios Breakfast table and the forest from South Park. I still hope someone who remembered got this one by Mugen Toons. But luckily, I have found two more stages, especially Weenie Hut Junior's and New York.
