The player can leave the normal playing area with this glitch. To perform it, go through the front door near the Protagonist's bedroom, and jump onto the doghouse. Then, jump onto the overhang to reach the roof. The player should then walk along the roof towards the back of the house, then jump onto the garage and finally over the wall. Drop down and the player will be out of bounds. However, as of the Kaleidoscope update, the dog house sometimes disappears, so this glitch is not always possible.
While crossing the roof, if the player is holding Tattletail, he'll say "Me know what you did!"
One of the most known glitches is falling out of the map. In order to do this glitch, the player needs to perform the out of bounds glitch. Then they need to walk to the map limit, and when they reach it, the player will fall off the map. Tattletail will start to glitch as the player falls.
Until the player reaches the map boundaries, Tattletail will be darkly-shaded , and his body will be missing, leaving only a pair of floating eyes.
