Alternate Titles: La tropa del trapo en la selva del arcoiris
The Happets feel the need to help other animals who are having a lot of trouble surviving, so they decide to go on a mission of solidarity that will take them to Rainbow Forest. There they will find a whole biodiversity in the form of Colourettes and Shadows and a dying Rainbow struggling for breath. The Happets are horrified because not only are the Colourettes in danger of death, so is the Rainbow, which is a symbol for them. Once again they’ll have to muster all their ingenuity, knowledge and team work to save the symbol of dreams and games.
