Old 90s videos we may or may not remember

Hey ok. SO.. I was on youtube and I came across some fun educational videos. Most are about dinosaurs, but one was about a "video-sitter" and she taught you things and sang to you a lot. Her name was Vitsie.

The other dinosaur things
I always thought this song was pretty kick @$$

And then the ending to this video is awesome about 50 seconds before the end is a good place to start if you dont want to watch the whole thing

If you remember any of this i think it would be cool to say so.

Also one thing I'm having the biggest trouble with. I remember a video I can't remember the name of. It has something to do with Rapping Rhymes. I dont know. But it was a real life video. Two main characters. I think one was named Darren? But the rapped/sung songs about educational things. I remember distinctly them doing songs about numbers, the [funky] zoo (elephants, sparrows, monkeys, walrus, kangraroos...) a sort of... rhyming one with three especially little kids. (bake=cake)
There was also a song about confidence with do-re-mi s.
A song about feet.
And then there was a really long song that was probably the first "updated" Cinderella story but it was rapped again. I don't remember the name of it or any of the songs so i can't find them on youtube. Help me?

EDIT: I forgot to mention that the video i was talking about also included random video clips from the Flintstones and Yogi Bear for some reason
