Six short video animations (Max 30 seconds each)

I'm wanting to make 6 short video animations as part of a children's science show.
The animations in look, and style i'm wanting very similar to a children's cartoon called Dipdap.
https://www.youtube.com/watch?v=b9tMaEGgJp8 - only in this instance, there will be a voice over talking to the character as it goes along. (The animations don't need to be provided with the voice over, as i will add that later)
A script for one of them is attached.
I have also attached some images of Dipdap, to give an idea of what i'm after.
