Layout
7-2, the final stage of the game, takes place in a massive castle belonging to none other than Wart. This is the longest level in the game, and it features multiple fights against Birdo. Also, it features a fight with Hawkmouth at the end, which comes to life and attacks the player before allowing them to advance to the final room, where Wart is fought. The Hawkmouth can be defeated by throwing the Mushroom Blocks in the room at it. Hitting it three times immobilizes the Hawkmouth, allowing the player to enter it and head to Wart's room. Wart attacks the player by spitting bubbles. He must be defeated by throwing vegetables that come from a vegetable machine in the room into his mouth when he opens it to spit bubbles. Once this is done six times, Wart is defeated, and the good inhabitants of Subcon can be freed.
