I found some cute Trigun videos on nicovideo.jp, a Japanese video website... And I uploaded them to youtube so you guys who aren't able to make an account (It's fairly easy if you google instructions) can view them! Please be aware that the quality has suffered a tiny bit...

Trigun Danjo Danjo [Please note that the person who made this video didn't complete the entire "Danjo Danjo" video in Trigun style... In other words, they never completed the video...
