Rosie flinched as her door was suddenly kicked open. When she whirled around to see what was the issue, she saw a panicked looking Akkorokamui and ShadowMoth.

“What!? What’s going on!?” She yelled at them.

“WE F*CKED UP!” ShadowMoth yelled.

“I THINK WE DIVIDED BY ZERO!” Akkorokamui yelled.

“...WHAT THE F*CK DID YOU TWO DO!?” Rosie yelled back. “Plagg, Kalkki, dual metamorphosis!” Rosie used the two Miraculous to transform into Black Gold.

“Follow us!” ShadowMoth grabbed Black Gold’s arm and dragged her along, with Akkorokamui following.

When they all got outside, Black Gold saw exactly what they did.

There, on the ground was a writhing mass of something. It was made of ink and the distinctive magic that was made when a Sentimonster was formed. And it was screaming in agony.

“...Let me guess.” Black Gold said very loudly to talk to them over the sound of the abomination screaming. “You two wanted to find out what would happen if an Amok and a mimic Amok collided, and then you two proceeded to divide by zero!?”

“...Oops.” Both ShadowMoth and Akkorokamui said in unison.

Black Gold sighed, and turned to the mistake of nature behind her. “...God I hope this works…Cataclysm!”

Surprisingly, it did. Since the abomination wasn't a Sentimonster in the sense of the word, Cataclysm worked, putting the thing out of its misery.

Black Gold then turned to Akkorokamui.

“Girl, please, don't make me seal off Koppi’s ability to mimic the Butterfly’s and Peacock’s powers, for the love of Star Clan.”

“Oh trust me, after that whole thing, I'm never using Mimic to copy ShadowMoth’s powers unless I have to.” She spoke, clearly shaken up.

And that is why you never collide an unstoppable force with an immovable object.
