Since Simon met Fionna and Cake, they've been thrust into a multiverse-hopping adventure together—a journey of self-discovery to restore magic to Fionna's world. Now, they find themselves in yet another dimension, searching for the magical crown that could both curse Simon and save Fionna’s world.

"We'd better be careful. Who know what kind of hazards we'll face here.." Simon murmurs, scanning their surroundings with a mix of curiosity and caution as he step deeper into the unknow. I hope we will find the crown soon.. He thinks with a small sigh. The weight of their mission settles heavily on his shoulders, yet this newfound sense of purpose drives him forward, determined to see it through—for Fionna, for her world, and, in some way, for himself.
