Bat Pat Season 1 Episode 19
Episode Title Over the Rainbow
Numerous rainbows appear over the Whispering Forest and turn it into a bright and happy place. The creatures of the Whispering Forest hate bright and happy, so they began fleeing into Fogville and even take over Natty's barn. But worst of all, the bright rainbows have made Martin's favorite Goth musician, Gothra, turn happy and sing happy songs.
