Enter the Nether portal and emerge at the border between the Crimson Forest and the Basalt Deltas. Minecraft® The Nether Portal Ambush is filled with mobs to battle as you pass through the forest’s ... mushroom-filled trees: 2 magma cubes, a hoglin with its butting head and a ghast shooting discs from its mouth. Be careful – if the ghast damages your portal, you might be stuck in the Nether forever!
