Bonus Episode

The Bonus Episode is the bonus episode of Captain Toad: Treasure Tracker. This episode has 18 levels (22 if the levels in the 2018 release are counted) and one boss: Draggadon.

This episode has no set theme or story. It is unlocked upon beating Episode 3. In the Wii U version, if the player has Super Mario 3D World save data on their Wii U, they will automatically unlock the first chapter, Expedition to the Sprixie Kingdom. In the Nintendo 3DS and Nintendo Switch versions, tapping a Super Mario Odyssey series amiibo will automatically unlock the Super Mario Odyssey Kingdoms chapter, which replaces the Expedition to the Sprixie Kingdom chapter from the Wii U version.
