Based on the character, not the real Mello!

WOAH! Marshmello was coming to Mexico! And obviously you would go to his concert, you had even prepared a gift for him, a Dr. Simi plush, with a recreation of his merch clothes and his helmet, it looked really good!

At the concert, you had to throw the plush onto the stage, the Dr. Simi hit Marshmello's helmet, he picked up the plush and looked around, showing it off to the public.
