There are Warp Pipes that can be found within the game's first and fourth chapters that strikingly resemble the Warp Pipes from the Mario series. Upon entering either Pipe, there will be a secret room with three more Warp Pipes along with 8-bit music playing in the background, which resembles the Warp Zone from World 1-2 in Super Mario Bros. Upon entering any of the three Pipes, they will warp the player to certain chapters within the game. Furthermore, finding all six buttons within the first chapter without the use of cheat codes will reveal a rainbow bridge that resembles the Rainbow Road track from the Mario Kart series that leads to a blue Warp Pipe, which takes the player to the secret room.

The second Warp Pipe is inaccessible in the PC version due to the switch used to access it not working; whether or not this inaccessibility was an intentional choice by the developers or a glitch is unknown.
