Just a fundamental invention Donut decided to make for Nathan. The miniature roller coaster was part of a mini amusement park set he was making, but gave up on. It was supposed to shrink people down to experience the mini experience personally.

He gave it to Nathan as a small little gift for him, but it seemed soon after Nathan tried it, something was off.

Nathan felt heavier and his room felt more.. tight.. he felt claustrophobic for a little, but quickly looked at the mini roller coaster.. it was, surprisingly, 5x smaller than before, which must've meant it caused Nathan to grow 5x larger.

He cried out to his mother, Issy, and his father, Desmond. They came running in, Kelly, Nathan's little sister, following behind them.

They were shocked and surprised at the sight and they quickly called Donut.

Donut was prepared to erase the device from existence, but Grim and Cyber-Fi suggested keeping it as a weapon, a tool of destruction to use against villains during battles.

Now, it sits in Grim's weapon storage and communicative hq, waiting for its time to finally be used.
