TMNT(2003) cancelled episode "Nightmares Recycled"

This one of the first pieces of lost media I ever got fascinated by as a kid, for those who don't know the 2003 4Kids TMNT series had an episode in season 5 that got cancelled about midway through production due to some new execs moving in and thinking the plot was way too dark. Said plot involved recurring villain "Garbageman" finally getting a backstory and hoo boy was it a doozy-he was originally a conjoined twin with none other then Hun himself, they were seperated in a back-alley by a doctor with acid and the Garbageman was discarded as well garbage, hence why his bases of operations were in a dump and a salvage scrap-barge. I'm not sure how far along the episode made it into production before getting canned, I believe the storyboarding and voice-acting was finished but the sound-effects and music weren't done yet.  This was also apparently the episode where Casey actually proposed to April so it's unfortunate that we missed out on that.

I'd love to see what was finished of this episode.
