Can you help me find an episode of Trollstopia for my daughter?

My daughter has been talking about ‘Holly’s Calm Floating Colour School’ and drawing pictures and singing songs about it. It has basically been every sentence that has come out of her for a week, I would love to watch the episode with her but it’s been removed from the streaming service we use. I would like to buy the episode but I cannot find anything about it when I google it. She says they mix colours, eat rainbow foods and meditate. There is a poem she recites that starts ‘an empty space stands calm and still.’ Any help you can give would be great as I’m really struggling with search results.
