Raph is attempting to get the high score on a video game, but Splinter interrupts, having caught Rat Flu. The Turtles are excited because they get to ask anything they want from Splinter, if they get to the 7th stage of rat flu. Splinter then lowers the temperature in the lair and shaves himself. He then enters Stage 2 and attacks the turtles. The turtles attempt to trap him in a giant hamster ball, but he escapes.


Leo: Give Raph-A-Doodle a hug!
Leo: Gesundheit.
Mikey: Omigosh! Omigosh! Omigosh! Splinter’s a zombie!
Donnie: Mikeyyy, zombies are interested in other people’s brains…
Raph: Rat flu. This is not a drill. I repeat, this is not a drill, boys.
Splinter: I feel terrible. Do I look terrible? Be honest.
Raph: You look great. Not horribly sick at all! …He’s horribly sick.
Donnie: URANIUM! We should absolutely ask for uranium! I mean—if I could finally get my hands on a little of that, we would be virtually unstopp—
Mikey: What about a brick oven for pizza?
Leo: Who’s gonna clean that? What we should ask for is matching unicorn onesies. Those are sick! Pun intended, and I nailed it.
Raph: Buckle up, boys. It’s about to get weird.
Donnie: Uh. Leo’s infected. Quarantine him.
Leo: Hey, you need me to get to the ‘Must Say Yes’ stage. We need to ask for the onesies—Whoa, it’s really hot. Is there a fire? There’s a fire here, right? The floor is made of lava?
Leo I’m gonna hug you ‘til a smile comes out!
Raph: …ENOUGH! Raph’s got this because in big time moments, leaders make big time shots, and I’m big time.
Donnie: He must say yeeesssss. Make him say yeeesss.

Splinter: Oh boy! Flu! Papa needs a new motorbike!
