After the Oompa Loompas perform the Augustus Gloop song, Wonka summons the Candy Boat, driven by many rows of Oompa Loompas. Wonka tells the kids not to lick the boat because then it will get sticky. The Oompa Loompas slowly row the boat farther down the Chocolate River, entering a dark tunnel. Wonka switches on the lights and the boat travels rapidly down a windy tunnel, passing strange rooms on either side. Finally, they reach the Inventing Room, where Wonka tells the Oompa Loompas to stop.
You first see the boat in one of Augustus's levels when he stops the river from flowing causing the boat to sit on the river bottom. After the river starts again you ride the boat to the Store Room 59 mini level.
