The episode begins with FM running from a hoard of T-Pose Zombies, with Fishy Boopkins looking from a window in his house. He comments on how the situation looks scary and decides to stay inside and wait until it's all blown over, then he decides to play VRChat. He then says "Let's go play!" probably breaking the 4th wall.
After numerous events, Boopkins finds himself in a room full of anime posters. He grabs a waifu pillow, and goes to sleep in-game.
Then, someone knocks on his real-world door. He goes to open it, humming on his way there, and when he opens it he found Waluigi at the door and he got infected, as shown in SMG4: War Of The Fat Italians 2018.
