RED NES is a boss that appears in every world. When you enter there's text that says RUN!!!. The music is a heartbeat with horror music attatched. About after 20 minutes a loud bellowing roar plays and RED NES comes chasing after you in his land , flying or swimming form. There are wrecked grave stones when you enter as well as fire in the background and no sky. When this happens he will attack with a mouthed tongue when in red water. When RED NES get's close enough to the player , the player get's demolished in 1 hit.
