The sound episode where they go to a haunted house. Music , that creepy organ sound, yodeling. It has it all.

I used to watch it but I vaguely remember its episodes. Probably one of the episodes the bus goes into the human body.

The digestive system, of course. Nothing makes me happier than to talk about all of that with 10-11 year olds.

The one where Arnold's skin turns orange because his body was full of beta carotene. Also the marshland ecosystem episode.

I don't remember ever watching that.

The one where it didn't exist in the UK!

Never watch that, I think

The one where she goes "das a bootyhole"

Hmm, I don't remember watching that

You're such a kid.

The one where the bus shrinks and wacky shenanigans ensue 😛 really I only have the vaguest memory of that show
