Irma slips between the crocodile's legs, grabbing onto his tail. The crocodile thrashes his tail, roaring as it turns to see what is going on. Spike hurls a knife that glances off his shoulder. The blade slices him, but not as deep as it should have.

"What?!" April turns. "How is that possible?"

"They've been perfecting the mutagen," Spike thinks aloud. "The turtles' cells regenerate faster than humans, and have much tougher skin. This guy is a little tougher." She draws her mace. "You okay, Irma?"

"Just dandy!" Irma yells, ducking a punch the reptile throws. "I'd love some help, though!"

Karai comes in high, kicking at the crocodile's knee. The creature glares down at her, snatching her up as if to crush her. His collar beeps.

April frowns at the collar and shakes her head. Spike smashes her mace onto the crocodile's fingers, and it lets go of Karai, swiping a huge hand at Spike. She dives out of the way, but not far enough. The crocodile's fist grazes her and knocks her to the ground. She rolls out of the way of the stomp that comes next. Casey stands back up and draws his baseball bat and charges. The crocodile bears down on him tossing him aside. Casey smashes his bat against the creature's arm to no avail.

The collar keeps beeping.

"That's it!" Irma shouts, stomping on the end of the crocodile's tail. "The collar! It's controlling him somehow! Agent Bishop must be giving him orders!"

"So what do we do?" April cries, slashing at the crocodile's arm with her fan.

"Try to take it off!"

"Can we destroy it?" Karai asks.

"It could kill him," Irma reasons. "I don't want to kill him, if possible."

Spike kicks up at the crocodile's stomach. "C'mon…"

Irma clambers up the crocodile's tail and locks her legs around his torso. She takes her dagger and works at the collar. "It's electronic! I need a passcode!"

"Can you hack it?" April asks.

Karai leaps up onto the crocodile's shoulders and joins Irma. She hands her a handheld device. "Try this." She climbs onto his head and slams her elbow onto the top of it. The crocodile stops and shakes his head.

"Hit him harder! Try to daze him!" April shouts.

Spike pulls out her Taser and tosses it to Karai. "Get him!"

Karai catches it, aims downward and fires. The crocodile shakes and drops to the ground.

"Okay, because of the mutagen he'll probably get up sooner than a normal person," Irma reasons. She applies the device Karai gave her to the collar and presses a button. The machine whirrs, and clicks as the collar falls off.

Irma climbs off holding it up. "We gotta take this back with us."

"Now what?" Karai asks, climbing off the unconscious reptile.

"Now we wait," Spike says.
