After getting the invite, Robotnik heads over to town to Sonic's place for the Christmas party at the exact time started.
Dr. Robotnik: I don't know if I should do this. But I shouldn't decline an invitation like this. So...
He knocks on the door and Sonic answers.
Sonic: Hey there Eggman.
Dr. Robotnik: Ahem. Hello Sonic. I've decided to accept your invitation and drop in.
Sonic: Awesome. Come on in. Don't try anything dumb, ok?
Dr. Robotnik: I won't.
They head into the dining room.
Sonic: Hey guys! My arch nemesis just dropped in!
Mighty: I'm going to kick your butt if you do anything stupid!
Vector: I'm going to Fus Ro Dah if you do anything stupid!
Dr. Robotnik: I won't. Oh, and I have a present for you, Sonic.
Sonic: Really? You do?
Dr. Robotnik: Yes. Here you go.
The evil mastermind gives Sonic his present. He opens it up and a boxing glove pops out of the box, punching him.
Sonic: Oww! That's a nice gift. I got a gift for you too.
Dr. Robotnik: Really?!
Sonic: Yeah. Here you go.
Robotnik opens up the gift and he also gets a punch in the face.
Dr. Robotnik: Oww! Thanks for the gift Sonic.
Sonic: You're welcome.
Dr. Robotnik: Oh, and everyone. I'm sorry for taking everything. I've realized now that Christmas is more than just presents, trees, and fancy lights. It's what's in the heart that matters. I think that once in a while, our enemies should get together just like this. That would make a great Christmas.
Tails: Robotnik's right. It really is a good thing to do.
Knuckles: Couldn't have said it better myself.
Ray: Yeah!
Amy: Oh, Sonic!
Sonic looks toward the doorway and sees Amy underneath the mistletoe.
Amy: I'm waiting...
Sonic: Oh no.
Amy: You know the rules, right?
Sonic: *Sigh*
Charmy suddenly pops out of a present.
Charmy: MERRY CHRISTMAS! WOOOOOOOOO!
The End
