While Alexis is outside doing her own training with the guys Alexis stops as he hears a splash and sees Chance go under the water and runs over with Jake and pulls Chance out.
"What's the big idea? Pretending to drone so I'll loose?" Jake asks.
"Yea are you trying to give us a heart attack?" Alexis asks.
"I uh just got a cramp." Chance says.
"A cramp huh. But your uh ok now right buddy. You cant swim can you?" Jake asks.
"Look don't make a big deal out of it!" Chance says as he starts walking.
"Why didn't you ever tell us?" Jake asks.
"You never asked." Chance says.
"Hey no sweat I'll teach you to swim." Jake says.
"Forget it! Fish swim I fly." Chance says as he walks off. Later as Alexis is trying to eat Jake comes running.
"Alexis emergency let's go I'll explain on the way." Jake says as they get on there way into the city.
"What is that stuff?" Kira asks as she sees some kind of ooze in the city.
"I don't know but we're gonna find out." Razor says.
"Things are not looking good buddy. What is that crud?" T-bone asks.
"Got me T-bone but its covered over half the city." Razor says as a giant frog jumps onto the Turbokat.
"What the? That frog thing is drooling all over my cockpit." T-bone says.
"Yea and its acid drool." Razor says as the drool starts making holes in the glass.
"I just washed the jet. Eat some g's toady." T-bone says as he tries to knock the giant frog off. The frog then breaks the glass over Razor and Kira.
"T-bone he thinks we're a couple of flies." Razor says.
"Maybe I can curve his appetite. Let go wart face! Aww crud he's gonna eat right through the controls!" T-bone says.
"T-bone maybe I can pry this over grown fly catcher loose. Activating upper missile launcher. Bon voyage froggy! Bingo! Happy vapor trails!" Razor says as he manage to get the giant frog off the jet.
"Uh-oh. Don't look now bud but your missile is on a collision course with enforcer head quarters ." T-bone says as the frog collides with enforcer head quarters as T-bone lands at enforcer head quarters.
"Radical you knocked wart face out." T-bone says as he hive fives Razor.
"Along with half my control tower." Feral says as he walks over with lieutenant Feral.
"Easy uncle Doctor Conway did say you wanted a live specimen to examine." Lieutenant Feral says.
"That's enough Felina. I'll handle this." Feral says as he walks over to the giant frog as Kira, Razor, and T-bone come over.
"Don't get any warts Commander." T-bone says as the giant frog then wake up and tries to attack Feral but Razor and T-bone shoo nets at it while lieutenant Feral shoots it with knock out gas making it fall unconscious.
"Your niece is pretty quick on the draw Commander." Razor says as some guards come over.
"Get that thing down to the biotech lab." Feral says.
"Yes sir." The guards say as they leave. The group then head down to the lab to find out what's going on with the frog.
"I'd stake my job that this is the work of Doctor Viper. You see there those DNA strips are coated with traces of catalyst x 63. Doctor Viper stole a shipment just last week." A scientist says.
"Viper. It figures that mutated sicko would be behind all this." Feral says.
"But can the mutation process be stopped Professor Conway before it destroys all of Megakat City?" Callie asks.
"Well Doctor can it be stopped?" The Mayor asks.
"Well perhaps with the proper anti mutagen chemicals. Oh yes the process can be reversed." Doctor Conway says as he mixes some chemicals and pours them onto the giant frog returning it back to its normal state.
"Then what are you waiting for Conway get to work." Feral says.
"Oh I'm afraid it's not that simple Commander. I'll need large quantities of these anti mutagens. And there's only one place in the city that has them Megakat Biochemical labs." Doctor Conway says.
"But that's right in the center of my slime covered city." The Mayor says.
"No problem Mayor. I'll get the chemicals personally. You stay put Felina that's an order and that goes double for you Swat Kats. The enforcers will handle this." Feral says as he leaves.
"Enforcers? What does he think I am kitty litter." Lieutenant Feral says as she leaves.
"I'd feel a lot better if you three were going along to help." Callie says.
"You heard the Commander. We wouldn't wanna break any laws now would we T-bone, Kira?" Razor asks.
"Not us. Of course if the Mayor ordered us to help I guess we'd have to as civic binding citizens." T-bone says.
"Well Mayor?" Callie asks.
"Ah well Commander Feral did say-" The Mayor then gets cut off by Callie.
"Fine just remember without those chemicals your going to be Mayor of Mutation City." Callie says.
"Don't just stand there Swat Kats go get that stuff and clean up my city!" The Mayor says. Kira and the guys then get going and find Felina and Feral stranded on a helicopter in the ooze.
"Looks like the enforcers ran into some trouble and it's still around." T-bone says as he avoids some acid spitting vines. Razor then fires some cutting missiles at the vines cutting the vines up.
"Nice shooting partner." T-bone says.
"T-bone. Feral and Felina are down." Razor says as T-bone then gets the Turbokat closer to the ooze to get Feral and Felina for the Turbokat to be pulled under the ooze by vines.
"The engines are clocked with crud. What are you looking at ugly?" T-bone asks as he sees giant eye looking in at him.
"Come on T-bone we gotta eject." Razor says.
"I'm with Razor." Kira says.
"We are not ejecting! Come on baby just one time for old T-bone." T-bone says.
"T-bone if your worried about swimming Kira and I will help you." Razor says.
"I am not ejecting and I'm not swimming. Come on. Come on! Come on! All three engines maximum thrusts. Yes!" T-bone says as he was able to get the Turbokat out of the ooze and then sees Feral and Felina cornered by a creature in the ooze.
"Razor!" T-bone says.
"I see them." Razor says as he fires a net rescuing Felina and Feral.
"Swat Kats come in. We got garble call from Commander Feral." Callie says as she comes in the communicator.
"Don't worry Mrs. Briggs he and his niece are with us." T-bone says as he drops Felina and Feral back at enforcer head quarters.
"Just get that anti mutagen Swat Kats before this glop covers every square inch of Megakat City." The Mayor says.
"We'll try not to let you down Mayor." Razor says as one of the engines quits working.
"Aww crud must of guzzled all of our fuel getting loose from that scum snake." T-bone says.
"Cant risk landing I the swamp again hot shot we're too big a target for those slime balls under the surface." Razor says.
"Rodger that." T-bone says as he lands on top of a building and the three get out on get skis blasting there way past some vines and mutated frogs.
"Next stop Megakat Biochemical." Razor says as a mutated creature appears.
"Razor look out!" T-bon says as Razor jumps over the creature as the creature then destroys T-bone's jet ski and sends him flying into the ooze.
"T-bone!" Razor says.
"Kira you stay here I'm going after him. T-bone if you drown I'm gonna kill you." Razor says as he dives in after T-bone.
"Your alright." Kira says as she sees T-bone and Razor.
"Are you ok buddy?" Razor asks.
"Yea but I think that ugly little thing bit me." T-bone says.
"Let me see." Razor says as he looks where T-bone got bit.
"Ow! Leave it alone." T-bone says as they then get on there way to the biochemical lab.
"You better see Doctor Conway after we get those chemicals. Sure you don't want me to drive?" Razor asks.
"Fine. Switching silent running maybe that'll keep those mutations off our backs." T-bone says as they enter the lab. Kira then shifts to wolf form as she walks with Razor over to a door as he tries to open it.
"Locked. Unlocked. Looks like we're in luck guys. The anti mutagens are still here give us a hand." Razor says as he then kicks the door open and goes into the next room with Kira. As Kira and Razor turn around they see T-bone mutated and get tackled by him and try to fight him off.
"I hate to do this buddy your just not yourself." Razor says as he fires a missile at T-bone pinning him to a wall as Callie comes in on the communicator.
"Swat Kats come in we've got big problems. It's Doctor Viper he's huge and he's heading this way. Razor, T-bone, Kira you've gotta do something. T-bone's a little tied up at the moment Mrs. Briggs but Kira and I will do our best. Now to call the Turbokat by remote control. Just hope the Turbokat has enough fuel to deliver this pay load. Wish us luck buddy if this doesn't work we're all gonna look like you." Razor says as they get on there way with the anti mutagens.
"There he is." Kira says as she spots Viper.
"Gotta get close enough to drop this stuff." Razor says.
"Watch out!" Kira says as Razor tries to avoid one of Viper's attacks.
"This is nuts T-bone would never let that slime hit the jet. Gotta bring her around and I'm running out of fuel." Razor says as Viper hits the Turbokat knock off the anti mutagens and sending the Turbokat spinning while he holds the anti mutagens.
"Aww crud flame out. Gotta eject. Now's our chance. Locked. Launch!" Razor says as he and Kira eject and start firing at the anti mutagens in Viper's hand. As the anti mutagens explode the blast sends Kira and Razor flying back and falling unconscious as they go under the ooze. As Kira an Razor come to they see T-bone and that he is back to normal.
"I thought you didn't know how to swim?" Razor asks.
"Hey I didn't know how to be a mutated frog either until today. Come on let's get the Turbokat and some flies for breakfast." T-bone says as he licks his lips.
"Flies?" Razor asks.
"Just kidding." T-bone says.
"Funny." Razor says.
