ROTBTD: Rise Of The Brave Tangled Dragons
This is their base :)

<Merida: Spirit of Summer, Guardian of Bravery/Courage
Hiccup: Spirit of Autumn, Guardian of Knowledge
Rapunzel: Spirit of Spring, Guardian of Creativity
Jack Frost: Spirit of Winter, Guardian of Fun>

This is one of the scenes I wanted to drew in one of my books: Guardians of the turtles.
It's a crossover between ROTBTD and TMNT 2007 version.

Also, the song isn't mine. I found it on YouTube. It's a perfect mix of theme 👌
