            IDEA:
            Mr Raccoon will fight on the ground, throwing himself and projectiles at the player.
            He will have a dash attack where he quickly rushes the player, dealing high damage on contact.
            He will also have a projectile attack where he throws pieces of trash at the player from a distance.
            He is meant to serve as a distraction and secondary threat while Neptune fights from above - meaning to overwhelm the player with multiple threats.
            0 - 50% HP: Normal behavior (Phase 1)
            50% - 25% HP: Increases dash attack speed and frequency (Phase 2)
            25% - 0% HP: Increases all attack speeds and movement speeds (Phase 3)
            If Neptune is defeated while Mr Raccoon is still alive, Mr Raccoon will flee the battle (run towards the ocean) - if he is defeated during this state, he will drop a vanity developer set.
