Meanwhile, in the city of Pensilvania, a vampire girl called Vampirina was with her human friends: Poppy and Bridget

That day, the three of them were going to a concert, where they were going to perform. They had played music since they were kids (since 7 years) and everyone liked their songs; at first, everyone was shoked to know that Vampirina was a vampire, but then they weren't scared anymore.
In that same day something happened, in the moment they were singing a song, Vampirina started to glow a purple light that everyone thought it was part of their show

Poppy: Vee, what is happening to you?

Vampirina: I don't know, it appeared out of nowhere!

Bridget: Eeek! It's scarring me!

Vampirina: I don't know what is it, but is not stopping!

Also in there, Sonic and his team were running with Shadow to find the owner of the blue Chaos Emerald, untill...

Rouge: Hey Tails, what is that glowing?

Tails: It's... the purple emerald! It most indicate that there a person who has the power of it!

Amy: Really?! Who is it?

Knuckles: (touching the emerald) I can see it's a girl, but not an ordinary girl, she has blue skin!

Sticks: Oh! Is it a monster?!

Knuckles: Actually it is! Is a vampire girl! I can see she has fangs and bat pony tails!

Shadow: Okay, let's spit up; I will get that girl and you will find the person of the blue emerald

Knuckles: Alright Shadow, she is at the park here in Pensilvania, and I can see she is on a stage

Manic: A stage?! She must be someone who makes music!

Sonia: Well... we should go now, we must find a blue owner

Sonic: Okay Shadow, I'll meet you in the city, okay?

Rouge: Good luck out there!

And then, Shadow arrived where that glowing was and he saw the vampire girl glowing the same color as the emerald; but he needed to hide, cause... Eggman's robots were already there!

Vampirira: AHHH! Let me go!! Or take this!!!

But Vampirina and her friends were already defending themselfs. Vee used her vampire abilities, Poppy get out a whip to get the robots out, and Bridget used a disc to make the robots dizzy. They weren't only a band, they were heroes!

Vampirina: Okay now is my...

Bridget: Vee, you're glowing again!

Vampirina: WHAT?!

Shadow: (thinking) Oh no! I better get them quick! The doctor is going to hurt them!

And Shadow wen't up to the stage to save them, and when he get there, they already get caught by the robots hands

Poppy: Ugh! Let us go!!

Bridget: Somebody HELP US!!!

Vampirina: I don't think someone will come, everyone get scared that they ran off

Shadow: HEY, YOU LOT!! Let those girls go!!

Poppy: What? Who is he?!

Bridget: Is he a monster?!

Vampirina: No... that's... that's a hedgehog!

Poppy and Bridget: A hedgehog?!

Shadow: If you wanna hurt them, you need to hurt me first!!

And Shadow destroyed all the robots with his Chaos Spear and let the girls free

Poppy: Oh my! Thank you

Bridget: Yeah, I'll never have gotten out, I didn't have a plan

Shadow: (thinking) She is kind of naive, just like Silver

And then he check on Vampirina, who he was more interesed about.

Shadow: Hey, you're alright?

Vampirina: (blushing) Umm... I'm... fine... at least... I think so

Poppy: (thinking) Did Vee blushed when the hedgehog talk to her? I think she now has a crush on him

Vampirina: Is that...

And Vampirina started to glow again

Vampirina: WHOA!!

Bridget: Ahhh! It's that glowing again!

Shadow: Again?

Poppy: Yes, Vampirina was glowing that light in our performance here

Shadow: So... your name is Vampirina?

Vampirina: (blushing again) Umm... yes, why? Do you know me?

Shadow: Yes, by this...

And Shadow showed her the Chaos Emerald that glowed the same light she glowed

Bridget: Wow! It glows like you Vee!

Poppy: So that gem is the cause of that?

Shadow: Yes, because it was calling her owner

Poppy: And that gem belongs to her?

Vampirina: Wait... you mean that I own that thing?

Shadow: That's right, it's your power

Vampirina: My... what?!

But then, Shadow's radio started to sound and it was Silver who was calling

Silver: (in the radio) Shadow, I got a problem!

Bridget: Who is that, sir?

Shadow: That's Silver, my friend who is calling, and he's kinda just like you

Bridget: (thinking) His friend is just like me? I wanna meet him

Poppy: Are they here in Pensilvania or in other city?

Shadow: Silver! Is there a problem?!

Silver: (in the radio) Yes, someone stole the yellow and aqua emeralds!

Shadow: What?!

Vampirina: Emeralds?

Poppy: So the gem he has is an emerald?

Shadow: Okay, I'll be there, but I need to meet up with Sonic

Bridget: Who is Sonic? Another friend?

Shadow: Yes he is, and I need you three to come too

Poppy: We will be glad to help! By the way, I'm Poppy and that's Bridget

Bridget: That's me! And what's your name?

Shadow: I'm Shadow the hedgehog, and I'm here to stop a creature who wants to destroy the world; and I need Vampirina's help to stop it

Vampirina: Of course I will help you Shadow! Cause you saved our lifes after all!

Shadow: (blushing) Well... uh... we should get going!

Poppy: (thinking) I think Shadow blushed when Vampirina said that

And the four of them headed to the another city, where they found the first person
