Detours are secret levels that are found in the main game. The level has RT instead of HWY before it's number and is viewed from the side and the player can only input a middle lane beat. Edit
Statue directions Edit
Each area has a level containing 2 tall giraffe statutes, and to unlock them, you must hit 8 beats in only certain lanes depending on which way the statues are facing (it doesn't matter if the beat you are supposed to hit is facing the wrong way). A bar should appear filling up after each correct beat. It will disappear if a wrong beat is inputted.
If the statues are:
Facing right: Right Lane
Facing left: Left Lane
Kissing: Middle Lane
Crossing Necks: Middle Lane
Facing Opposite Directions: Right then Left Lane repeatingFacing Up: Unknown

-It is possible to play Detour levels in Expedition Mode, and if the player has not completed them yet, they can be added to Perfectionist mode. This is the best strategy for unlocking all Detour levels.
-It is not required to play the Detour levels to unlock the "Seen It All" achievement.
-Pleasant Plains uses the song from the splash screen for the Studio Bean logo.
-The levels with giraffe statues are always the second one of a world.
-The route numbers of the detour levels follow a pattern with the exception of Desert Divide and Heavens Hall, which are outliers.
