17 years later...
Kee-Tai meditating in his room in the Student barracks. He does so, until he hears voices nearby.
Voice: He he he he he...
Kee-Tai goes back to meditating but hears the voice again. He leaves his room and sees his brother Chie-Po waiting outside of Peach's room.
Chie-Po: Oh hey! Morning, Ke-Tai.
Ke-Tai: What's going on?
Chie-Po: Sssssssh!
Ke-Tai has a confused look on his face.
Chie-Po: I'm about to pull the best wake up prank on Peach ever! This is going to be epic! Wanna watch, big brother?
Ke-Tai: Don't be ridiculous, of course I don't want to... *gets closer to Peach's room* Ooh, this does look good.
Kee-Tai observes, how Chie-Po setting up his prank, while Peach sleeps. Chie-Po places a bowl of pudding on the floor and uses a pulley system to raise Peach's bed up.
Chie-Po: Peach... *giggles* YOU'RE LATE FOR TRAINING!
Peach: *wakes up* COMING! *leaps off her bed but falls right into a bowl of pudding.
Her brothers laugh as Peach falls for the prank. Peach gets up upset and her bed falls on her, knocking her out.
Chie-Po: Te he he! Gotcha ya! You've been Chie-Po-ed.
Peach: Ha ha… Good one. Got me again! Lucky for you, I'm not petty or revengeful or... *tries to dive after Chie-Po, but misses and falls to the floor.
Chie-Po: *runs away* Come and catch me!
Peach: *runs after him* You'll pay for that.
Kee-Tai: *just looks after them and sighs* Am I really related to them? *goes back to continue meditating in his room*
The scene switches to outside the Training Hall, where Po is talking to Shifu.
Shifu: I don't like it Po, not one bit. Master Yao should be arrived now. Good heavens, you don't suppose something unsavory happened to him.
Po: I'll send out Peach and Chie-Po to look for him at once.
Shifu and Po observe Peach and Chie-Po landing on each other outside the Training Hall. They continue to fight, until Peach sends Chie-Po crashing into some debris.
Peach: Looks like the Chie-Po-ster just got Peach-ed. *laughs* Ha ha ha ha ha...
Chie-Po is seen slowly coming up.
Peach: *worried* Are you okay, little brother?
Chie-Po: *turns around and appears to have no legs* My legs!
Peach: *shocked* Ahh! Oh, no! Chie-Po, forgive me. Oh, Chie-Po! *cries*
Chie-Po: *rolls apart and quickly reveals his legs* Gotcha you again, big sister!
Peach: *dives after Chie-Po* Argggg...
Po: *walks up to them* Peach! Chie-Po!
They get up and bow to their father.
Peach: Father. When did you get... Whoa! *looks at the debris she and Chie-Po created* How did that happen?
Po: How many times, I told you, that this little prank war between the two of you must stop.
Peach and Chie-Po: She/He started it! *points to each other*
Po: I don't care who started it. I want it to end before one of you goes too far and does something you regret. Is that clear?
Peach and Chie-Po: *sadly* Yes.
Po: Master Yao must supposed to arrive at the Jade Palace last night. I need...
Shifu: I need.
Po: *sighs* Master Shifu need... but mostly I need you to find him and...
Shifu: ...escort him back here at once. And now go! Hop, hop!
Peach and Chie-Po look at their father.
Po: *sighs and nods* Go!
Peach and Chie-Po exchange looks and head off into the Bamboo Forest.
