Within the data for Chapter 4 is an unused minigame for the Mike Zone. This minigame is a Flappy Bird clone based on Small Mike's "Applause" attack which uses the microphone mechanic to replicate the mobile game's use of tap controls. Points are scored based on the amount of time the player spends in a round rather than the amount of microphones (which fill in for Flappy Bird's pipes) that they pass. The speed of the minigame increases as it goes on, and microphones eventually start appearing at visible angles rather than straight up and down. Given the minigame's roots in one of Small Mike's attacks and that the minigame uses the same high score counter as Battat (Small Mike's minigame in the PC and console releases), it's likely that the former was eventually reconfigured into the latter.
