The cellphone attacks?
Presumably because you didn't call Papyrus enough, jerk!

ATTACKS:

• Loud ringtone: shoots musical notes at you!
• COMBO: Strings multiple Loud ringtones together. Gets painful fast.
• Unknown caller: Gibberish flies in confusing circles!

ACT:

• CHECK: 2 ATT, 10 DEF; a sturdy phone given to you by Toriel. It sure looks aggressive right now.
• Hang Up: Ends a Loud Ringtone streak.
• Block caller: Disallowed use of Unknown Caller for a few turns.
• Throw: "The phone is too sturdy to be broken by throwing. Try fighting?"
• Kiss: "Your phone isn't sure what you're trying to do, so it provides a dialtone instead."
• Update & Restart: "You reboot your phone and it seems happy again. Good."
