Remember how Noggin ended up becoming Nick Jr. in 2009? Several bumpers were lost, including this one. On Martin Luther King Jr. Day 2016 the bumper was found. You can watch it here. It's not in Stereo though.
UPDATE: 2/29/16 Unfortunately, this video was taken down by Viacom due to copyright. Although, there are many other videos of this rare bumper, but in potato quality. Just now, Robowil, one of the many LMW regulars, revealed he downloaded the video last month. The proof is below. He is, however, not going to share it at all. Bummer. :(
Message from Robowil: I may upload the bumper on my Google Drive account, but the chances are slim, since I still have to make it public.
