On Halloween night, while Ranger Canyon leads three small Squirrel Scouts on a haunted hike, Daisy sees a ghost and Elliot and his friends help investigate.
The Walnut Cup, the only American stop on the World Squirrel Soccer League tour, is taking place in Elliot's park, but when the game ball, a perfectly round walnut, goes missing it is up to Elliot and his friends to find it.
