Princess Bubblegum would also be a great main character. She's intelligent and resourceful. If there was a dragon in the school, she could study it scientifically, or try to find ways to use its powers for the good of the Candy Kingdom which the school might be a part of. And she could also be in charge of making sure the dragon doesn't cause any chaos.

Finn and Jake are obvious choices. Finn's brave and adventurous nature would make him a great character to explore the Jungle School's mysteries. Jake's shape - shifting ability could come in handy during various situations at school, like sneaking into restricted areas or helping in physical challenges.
