Hi there.

I am trying remember the name of a Christian series for kids. It was about a brother and sister in their playroom. I think it was from the 90s.
The brother and sister were humans, but dressed in weird costumes and hair made of coloured foam, or something like that. Most of the other characters were puppets.
The brother would always perform the same rap before they watched a story.
There were a lot of songs and dances by kids.

I do remember in one of the episodes, there was a rocket launch and some guy was singing the ABC song in opera style to Sprach Zarathustra by Strauss.

I know this must sound very strange, and the details are really vague, but that's all I can remember, and it's frustrating that I can't remember anything else - especially the name of the series!

Please help me before I drive myself insane.. Thank you in advance.
