The heroes and the Council of Happiness swap jobs, and when the council fail their quest, the whole forest is at risk of being flooded by Stinkystuff.

The heroes are made to clean the Cave of Mirrors as punishment for frolicking before a quest is complete, and they accidentally release the Party Harpy.

The heroes set out on a quest to find out who is draining colour from the forest and muster all their positivity to save it from greyness.
