Catboy, Owlette, and Gekko were all meditating at the pagoda on Mystery Mountain, when suddenly they hear a loud distant thud.

*THUD*

PJ Masks: Huh?

Gekko: What was that?

Catboy: I don't know, but it came from the cave! C'mon!

The PJ Masks start running down the mountain. The thud noise is heard again.

Owlette: Owl Eyes! Guys! I see An Yu heading for the cave!

Gekko: An Yu?

Catboy: Something must be really wrong! Let's hurry!

Once the PJ Masks arrived at the cave, they see An Yu using her flute to put a rock back together.

An Yu: There you go old friend.

Gekko: Oh hey An Yu! What are you-

An Yu: *holds staff up* Shh! Listen. . .

*slicing sound*

Catboy: W-What was that?

An Yu: *runs into cave*

The PJ Masks follow An Yu into the cave and find no one other than Batarina slashing at rocks.

PJ Masks: Batarina?!

An Yu: You know this mountain destroyer?

Owlette: "Mountain destroyer?"

Batarina: *notices others* Oh hi PJs! Hi other person with PJs! Wait, who are you?

An Yu: I am An Yu- Protector of Mystery Mountain. And it is my duty to stop you from destroying my mountain any further!

Batarina: Relax Yu An! I'm just practicing my, Super Bat Claws! 

Batarina is about to slash a rock in half, when An Yu quickly taps her staff on the ground and it transforms into a flute. Then An Yu plays her flute and Batarina starts floating in the air.

PJ Masks: *gasp*

Batarina: Whoa! *giggles* This is kinda fun!

An Yu(unamused): *plays flute again*

Batarina: *falls and hits the ground* I'm oka- Holy Flap!

Batarina looks up and see An Yu flying towards her with her staff extended and Batarina quickly jumps out of the way before she and An Yu's staff collided. Then An Yu played her flute again and pined Batarina to the ground by moving a rock onto each of her arms. But suddenly the rocks float off of Batarina's arms and roll away.

An Yu: Hm?

Gekko: *deactivates camo next to Batarina*

An Yu: What are you doing? I had just captured this villain.

Gekko: What? No, Batarina's not a villain!

Catboy: Yeah! She a hero like us!

An Yu: A hero?

Owlette: I know it's hard to believe,

Batarina: Hey!

Owlette: But she wasn't trying to harm the mountain.

Batarina: Yeah! *stands up* I was just training!

An Yu: *looks at Batarina* Hmm, I will believe your excuse for harming my mountain.

Batarina: Excuse?! *is about to walk forward*

An Yu: *points tip of staff at Batarina* For now.

Batarina: Uh, okay. Sorry for wreakin' your rocks or whatever. *rubs back of neck* I should of asked if it was okay first.

An Yu: *small nod* *flies back to the pagoda*

Batarina(confuses): Hmm. . .

Gekko: *puts hand on Batarina* You'll get used to her, eventually.

Batarina: Yeah. . . eventually.

Catboy: So Batarina, if you wanna keep training, wanna train with us?

Batarina: You bet!

Owlette: But no slashing rocks and trees this time.

Batarina: Okay. *giggles*

PJ Masks: *laugh*
