Infinite Tunnel

The is a tunnel found in present-day Harrisville. The whole goal of the Infinite Tunnel is to go through the tunnel and beat how long the player has traveled through it. In Yo-kai Watch 2, the length of the Infinite Tunnel is affected by how the player answer question asked by people inside of the tunnel.

In the Infinite Tunnel, the player may or may not encounter Yo-kai or receive items. The player can walk through the infinite tunnel once a day which resets always on 6AM, based on the clock system of the Nintendo 3DS.

At 2020 yards, the usual brick of the tunnel will be changed into a dilapidated wall, at 5050 yards, the tunnel will appear cleaner and mall-like, with shiny reflective floors. The tunnel seems to loop around 10050 yards, where the tunnel and the Yo-kai seem the same as the first time when encountering them. However, the Yo-kai will be much stronger than before.

 * The player can escape by going through doors or just continuing.
 * The players are able to find exclusive Yo-kai when in the Infinite Tunnel, including Crank-a-kai Exclusives.
 * At the end of the tunnel, the player will find a Mirapo which will transport them to the beginning, and Moody Mary on top of the lake. Mallice may be yelling at Moody Mary on the left of the lake.
