RAT

The mafia boss spun their chair to face a lineup of disposable mooks. "You're here because one of you is a dirty rat."

"Hey!" a mouse-faced goon said. "I shower every day!"

"It wounds me to suspect any of you. However, you five were the only ones who knew what bank we'd be hitting last night. None of you are leaving this room until I figure out which one of you squealed."

The porcine thug of the lot said, "Now that's just mean, boss."

"And once I find out whichever one of you sold us out, well, let's just say you'll be sleeping with the fishes."

"Look, I get that all the time," the dolphin man said, "But dolphins are mammals. Mammals!"

"I'll give you this one chance to speak up. Confess to your sins, because trust me brother, you don't want to know how many ways I know how to skin a cat."

The feline grunt hissed. "You can't seriously believe it'd be me. You know how many lives I gave for you."

The don looked over the men dispassionately. "No takers? You got nerves of steel keeping quiet, I'll give you that."

The four animalistic mooks all turned as one towards Izuku. Izuku asked, "Can I eat these nerves?"

"Unfortunately for you, I happen to be something of an Among Us expert." The don grinned. "I thought it'd be perfect for practicing kills, but I got really good at spotting the traitors instead. The killer would always slip up somewhere. Maybe a camera caught them heading somewhere they shouldn't. Maybe they tripped a sensor going out one of the back doors. Or maybe…"

The don turned to Izuku, "They set off a metal detector when they walked into this room."

The other mooks gasped. Izuku tilted his head. "I did set off the metal detectors embedded in the door frame. My bones are composed of metal alloy."

"Very true, my metallic friend," the don said, puffing on a cigar. "It makes an excellent alibi. Problem is, you're the only one with anything metallic on you. Everyone knows that snitches carry wires on them. If no one else has a wire on them, you're the only one it could be. Goodbye, Midoriya."

The villain pressed a button. The floor opened up underneath the dolphin man, and he plunged into a tank of water.

"I'm okay!"

A shark swallowed him whole. From inside its stomach, they said, "Still okay!"

"Whoops, wrong one."

He pressed another switch. A mousetrap slammed over the rat man. He wheezed as he struggled to free himself.

"Could've sworn I ordered these right…"

Another switch dropped blades from the ceiling. The cat man yelped as his back got sliced off.

"Did I color code these?"

The green button dropped a metal hook. The pig mook squealed as it dragged him towards the nearest chinese restaurant.

"The last button has to be right!"

When he pressed it, his cigar exploded. Izuku said into his wire, "Mission accomplished."

The don falls down a hole, shouting, "Wrong button!"
