The Centuplets

"Take my weapons with you. They are the only way to beat these nightmarish creations, if you wish to beat them" - Ezra upon his defeat
Massive credit to the creator of the sprite.

The Centuplets are a hard War Mode, Post-Phantom, Expert-Exclusive boss.

Summoning
The Please Fricking Stop must be used at night to summon The Centuplets. It is dropped from War Mode Eye Bosses with a 1 in 1000 chance if they are beaten hitless and Ezra has been defeated, but can also be bought from Ezra for 99 ultroofium coins after he has been beaten twice hitless.

Attack Pattern
All eyes will circle around you. They will then use the attack pattern:

One eye will shoot flames that inflict a random really bad War Mode debuff, or Lasers. This then switches to another eye, and repeats again and again.
