"Redstone Baby" is a song by Antimo and Welles that plays during the ending credits of The Last Place You Look. The vocals were performed by Skyler Barto (Antimo).[2] In the story, the same song is called "Symphony in E", a composition by Soren to celebrate his discovery, and it plays when Jesse and Olivia enter his laboratory.
In a marshmallow world, you're my sweetheart
In a marshmallow world, you're my sweetheart
You're the bed to my rock
The flint to my steel
My redstone baby doll
My redstone baby doll
In a marshmallow world, you're my sweetheart
In a marshmallow world, you're my sweetheart
My sugar baby[3]
