Odd videos for kids
As I learned from the youtuber KVN AUST, you can search generic file naming schemes to find obscure youtube videos. A particularly fruitful one is "AVSEQXX," where XX is replaced by two random digits.
A consistent theme I've seen is different channels uploading edutainment from seemingly the same source. One type I've seen are these parables told in the same format. One such example is "The fox and the grapes," uploaded under the title AVSEQ67 which features a fox with a rather amusing voice.
I've also seen many animated shorts featuring this reaccuring rat character, featured in the image above. An Indian flag is featured in that video, so I'm assuming that's where it's from. See the following links for those:
AVSEQ93 AVSEQ12 AVSEQ66 AVSEQ56
Music set to cartoons
I've seen two of these, so I'm assuming there's a pattern. AVSEQ22 seems to feature a Chinese children's song set to random footage from the Heathcliff animated show. I've also seen the same done to an early looney tunes short.
