Poor Pikachu's face becomes a map of pain, and his bleeding mouth emits only strange syllables that the human mind cannot process.
Go outside, and you'll find that the whole world has transformed into some kind of post-apocalyptic horror infested with demons. Pikachu offers no comfort, only the cold embrace of the void that has replaced his face ...
"BEHOLD SUCH BEAUTIFUL HORRORS, AND WEEP FOR JOY."
Don't go back inside, though. Remember: Inside-Pikachu's face has devolved into a mass of bloody tentacles. But he's still your pal. He still wants to give you a kiss ...
"NO. STAY. JUMP INSIDE."
