Mountain Marvel is the fourth episode of the twelfth season.
Peter Sam rushes to finish his jobs in order to hear a tale about Proteus from the famous storyteller, Miss Marvel. During this, he stumbles across a neglected statue of Proteus and vows to hide it until the ceremony. This results in a disaster, but Peter Sam figures out a way to fix everything and make it in time for the storytelling - complete with the statue on display.
