Red Realm
Red Realm is the sixth and final major area of Rodney's Tunnel consisting of floors seventeen through twenty. It is a fiery fortress inside an open cave with lava and magma rivers on the ground. Unlike other areas, enemies are able to spawn inside chest rooms here. It is also unlike anywhere else because every single floor has a unique title, despite sharing music and theming.
Several enemies from throughout the game are reused in these levels and the only new enemy is the Red Man. Rodney is fought at the end as the fourth and final boss.
