Get Malachite (and the surprise) down from 50 health points to zero. Switch between Garnet, Amethyst, and Pearl with C. Use a Gem's weapon with Z. Use Steven's Shield with X. The Shield has a limited amount of time to use, but will recharge. Watch for signs of attack from Malachite to summon Rose's Shield. Have fun with the surprise! Note: This game was made months prior to "Super Watermelon Island", so the fight is definitely not canon. I might make a Malachite Fight 2 for In Too Deep though ;)
