Look up the original Tik-Tak from the BRTN. it's non spoken animation with shapes, sounds and music. Great for toddlers. All the music is ingrained in me :D
Other good show from the BRTN was "Er was eens". They are split up in 4 main "seasons: de mens, de aarde, de ruimte and het leven.
History, how earth was formed and evolved, space and human biology.
Dutch and French, I'm not sure if it was ever dubbed English, but my kids watched this on repeat.
