Switch Scramble Circus
From the Super Mario Wiki
Switch Scramble Circus, also known as World 1-5, is the fifth standard course of World 1 in Super Mario 3D World. It is a large colorful circus with Switch Panels. An interesting thing to note is that the music in the course changes depending on the section. The course is unlocked by completing Mount Beanpole and its own completion unlocks Bowser's Highway Showdown.
This course begins in an area filled with Biddybuds and Switch Panels, which need to be activated in order to gain access to the next area. The same must be done in the next area, where Stingbies and moving platforms are now present, along with an Roulette Block. A Checkpoint Flag and an area with Para-Biddybuds follows. A straightforward area with Biddybuds appears soon after that. The player then reaches another Switch Panel area with a Magikoopa present. A Clear Pipe takes the player to the Goal Pole.
Atop the platform closest to the Goal Pole is the course's stamp. If the player activates all the switches in that area, the platform will fall down. The stamp is Super Bell, which can be collected via Spin Jump. If the player is not using Rosalina, then they can accumulate the stamp by Wall Jumping.
On the first spade-shaped mirror at the beginning of the level, an 8-bit Luigi can be seen running in its reflection.
