The ultimate showdown! This is a multi-phase battle against both Antasma and Bowser. Ensure you are fully healed and stocked with Max Mushrooms, Max Syrups, and 1-Up Deluxes before entering.

Phase 1: Antasma & Bowser
- They attack together. Bowser uses powerful physical attacks and fire breath. Antasma uses dark magic and summons 'Antasmunchies' (which can be eaten by Bowser to heal him, so defeat them quickly!).
- Strategy: Focus all damage on Antasma first. He is the squishier of the two. Use your strongest Bros. Attacks like 'Luiginary Wall' or 'Star Rocket'. Dodge Bowser's attacks carefully. If Bowser eats an Antasmunchie, he heals significantly, so prioritize defeating them with multi-target attacks or by having Mario jump on them.
Phase 2: Dreamy Bowser
- After Antasma is defeated, Bowser absorbs the Dream Stone and transforms into Dreamy Bowser, a massive, powerful entity. This triggers a 'Giant Battle'.
- Strategy: This is the final Giant Battle. Dreamy Bowser has incredibly powerful attacks. You'll need perfect timing on blocks and dodges. He has a unique attack where he summons a giant fist; swipe to dodge. He also breathes a massive fire stream; swipe up to jump over it. Use your Giant Mario special moves whenever they are charged. This phase is a pure test of reaction and endurance.
Reward: Game completion, credits, and the satisfaction of saving Pi'illo Island!
