Chapter 1

About a day after bringing Fern under her wings, Bella introduced the newt to her art room, where all her collections and drawings and paintings go. When Fern takes notice of a large painting depicting one of Bella's earliest adventures, the demon decides to tell the story.

Before she departs for Gravity Falls, SpongeBob's pet snail, Gary, gets snail-napped, and she, along with new friends Rudy, Penny, Snap, Lincoln and the Loud Sisters, go on a journey with SpongeBob and Patrick to get him back, unleashing new bonds of friendship and courage.
