Oscar and Hedgehog discover a new structure on the island and become friends with its caretaker.
Tropes:
- Bears Are Bad News: The spotted bears. They are meant to protect the island in case of an emergency, but if they are woken up before then, they attack anyone else. The music of the Soundhouse is meant to keep them asleep in the meantime.
- Creative Closing Credits: "Witches Lullaby" plays during the credits, indicating it's a "lore-building" episode.
- Lighthouse Point: We learn the tower that looks like a recorder on the island is called the "Soundhouse", but unlike a lighthouse, it produces sounds with the purpose of keeping the spotted bears asleep.
- Music Soothes the Savage Beast: The Soundhouse's music is to keep the spotted bears from waking up and attacking the island.
- Rube Goldberg Device: All the devices in the Soundhouse work this this. In fact, the engineer who designed them is named Barb Goldbergnote .
