Outside the party, there was Eggman and Romeo attacking the city, and Sonic with the Pj Masks transformed came out to stop them.

Sonic: Eggman! Romeo!

Catboy: Stop this now!

Eggman: Sonic?!

Romeo: And the Pj Masks too, like always

Eggman: But... Sonic wasn't supposed to be here as I thinked

Catboy: Well... it was our graduation that I invited Sonic to come...

Sonic: Untill you ruined the fun!

Eggman: No matter! Me and my nephew are going to stop you!

Shadow: Your...nephew?!

Vampirina: Romeo is related to you?!

Romeo: Yes batty girl! I'm Romeo Robotnick, Dr. Eggman's nephew

All Pj Masks: WHAT?!

Sonic: It... it can't be!

Silver: How... it could be possible?!

Tails: So that's why Romeo had Eggman's radar!

Chase: Is it true?!

Shadow: You are the doctor's nephew?!

Romeo: That's right, black pest!

Skye: Well, whatever! We will stop you no matter what!

Chase:(thinking) I never see Skye that angry

Sonic: Yeah! This city is not yours!

Catboy: So we will stop you NOW!

???: I don't think so!

And then, some sticky splats get Sonic and the others inmovilized and they can't move

Sticks: Eww!

Sonia: Ugh! What is this thing?!

Owlette: I think I know who might be behind this sticky situation!

Gecko: I know it too!

Espio: So who is it?!

Catboy: Night Ninja!!

And they someone covered in a black outfit just like his helpers

Silver: Is he a ninja?!

Espio: But I don't a good one just like me

Night Ninja: So you are the guys that help the night insects!

Gecko: Excuse us?!

Sonic: What?! Did they told you about us?!

???: Not only to him

Catboy: Who was that?!

Sonic: Oh... I think I know who is it

Blaze: Yes Sonic! Is someone who we know!

Silver: I also know who is it too!

Espio: Sure Silver, is your enemy from the future

Bridget: Huh? The future?

Silver: Yes Bridget... I actually come from the future, 200 years from now

Bridget: Wow! That's a lot of years!

Espio: Look Silver! It's...

Sonic, Tails, Silver and Blaze: Eggman Nega!!

And they saw someone who looked just like Eggman

Shadow: Eggman Nega! How did you travel here?!

Eggman Nega: Well... these three came here to help me, so here I am

Catboy: So... you are from the far future?

Night Ninja: Yes he is Catboy, he is actually this doctor descendant that I brought thanks to your dragon friend's stick

Catboy: What?!

Tails: By "dragon friend", you mean is An-Yu's stick?

Knuckles: But... where is she?

Eggman Nega: Hehehe! She is right here!

And Eggman Nega showed a gong with a dragon picture

Gecko: Huh?!

Owlette: What?!

Knuckles: She is... in that gong?!

Catboy: What?! How?!

Romeo: Me and my uncle used our genius to seal her in that gong so she can do whathever we say to her

Sonic: An-Yu would never do that, eggfaces!

Catboy: Actually she can Sonic! When she is the dragon of the gong!

Sonic: What?! No way!!

Blaze: Well, prove it!

Night Ninja: As you wish... cat princess!

And he hit the gong to reveal the dragon inside of it

Dragon An-Yu: What are your orders, master?

Silver: Master?!

Shadow: Doesn't she can get out of that gong?

Catboy: Yes, but we need her stick, that's the gong's hammer

Vampirina: But they got it!

Eggman: Night Ninja! Tell the dragon to get rid of this pests!

Ninja Ninja: You heard that dragon? Get rid of this heroes with your breath!

Dragon An-Yu: As you wish, master

Espio: I don't think so!

And Espio let free everyone

Poppy: Espio? How?!

Gecko: Wow! How did you do that?!

Espio: It was just my ninja training

Catboy: You're a ninja too?! Cool!

Romeo: What?! Argh!

Night Ninja: No one is better ninja than me! Dragon, attack them!!!

Catboy: Watch out!!

Catboy: I'm... okay Owlette, don't worry...

Blaze: I can't beleve that those villains have done that to you

Amy: Me either Blaze, I can't beleve that An-Yu can do this to you

Sonic: Well girls, we have to stop those thieves before they do something with our chaos powers
