What are some nice short videos for youngish kids to watch?

I have kids ages 4-7 and they quite like watching a little snippet of something while they brush their teeth.

One thing they have been into recently is these stop motion videos on youtube on a channel called Peapea. However, it's obvious that M&Ms and Coke give them lots of money because it's all you see in many of the videos. But these are good videos, as the kids like them and while the full youtube videos are 30 mins long, within this there are lots of shorts only a few minutes long each. Perfect for bushing teeth. Also a bonus is those videos don't rely on sound, so they can watch and understand it without telling each other to brush queiter.

Does anyone have suggestions for anything similar that isn't plastered with Cocacola and is suitable for the 4-7 age range?
