A bunch of boss ideas I had. We can use any of them, all of them, or none of them Overgrown goldfish: The very first boss, found at the coast. It would fly about the arena (probably a hilarious early failure of the scientists) and slam into the walls to attack. Beating it unlocks swim. The Shoal: First cave route boss, found in the sea. This would be more of an arena type fight where waves of piranhas would spawn in followed by the boss. Beating it unlocks the feeding frenzy Naga: First volcano route boss, found in the forest. Would dangle from the ceiling, dripping acid and biting down. Beating it unlocks walljump.
