The Approach
To complete this stage and unlock the next island, you must defeat a trio of baboons known as Ba-Boom, the Boisterous. Select your preferred partner from the Buddy Barrel near the starting point, then follow the path to the right and begin the encounter.
Phase 1
During the battle’s first phase, you must face all three members of Ba-Boom, the Boisterous. These baboons all possess similar equipment and abilities, but each is marked with a distinct color. As you progress through each phase of the battle, use their brightly colored snouts and wristbands to keep track of which enemies you’ve successfully damaged.
Early in the battle, these baboons alternate between two basic attacks. When you spot one of these enemies attaching a rope to the beam above you, it indicates an impending swing attack. If the incoming baboon is upright, jump over the enemy as it swings low to the ground.
If the baboon swinging toward you is upside down, jump up and bop the enemy as it approaches. A successful counter forces the damaged enemy to reset, but the remaining baboons are free to continue the attack. Continue to evade or counter each incoming enemy until the entire group switches tactics.
When two of the baboons drop to the ground, it indicates an impending roll attack. Jump over the enemies as they speed along the ground to keep yourself healthy for the duration of the attack.
After a few passes along the ground, the baboons crash into the support posts on either edge of the area. Move quickly to bop both of the dazed enemies before they recover.
To complete the first phase, you must hit a single enemy with three successful attacks. You have no control over which enemies will be vulnerable at any point in the battle, so it’s best to counterattack at every opportunity. When you defeat one of the enemies, the two remaining baboons begin the battle’s second phase.
Phase 2
During the battle’s second phase, the remaining members of Ba-Boom, the Boisterous introduce some new attacks. After a brief tantrum, the baboons flank you and begin tossing explosives to the ground. Keep your distance from the spiked red bombs—even before they detonate, these bombs are very dangerous. When a Watermelon Fuse Bomb appears in the area, however, try to toss it back to one of your attackers.
As more bombs are tossed into the area, it can be difficult to avoid the resulting explosions. Use the fuse attached to each bomb to determine exactly when it will detonate. Stay healthy, and take every opportunity to throw a Watermelon Fuse Bomb at one of your attackers. If you’re quick, you should be able to land multiple hits before the baboons switch tactics.
When the baboons finish throwing bombs, they drop to the ground and begin leaping around the area. Avoid the enemies until they give you an opportunity to land an attack.
Between leaps, the baboons sometimes cling to the support posts or stop to scratch their legs. After a baboon slams its fists into the ground, however, it flips into the air and lands on its head. This is your chance to attack—jump up and bop the vulnerable enemy before it recovers. Repeat the process until you defeat one of the baboons, or until they switch back to throwing bombs.
With only two remaining opponents, it shouldn’t take long to hit one of them with three successful attacks. Stay healthy and defeat one of the baboons to begin the battle’s third and final phase.
Phase 3
When the battle’s final phase begins, the remaining baboon summons the specters of its fallen comrades. The new members of Ba-Boom, the Boisterous link hands to create a large pendulum. As the baboons sweep back and forth across the area, they toss bombs into the air. Avoid touching the baboons, and keep your distance from any red bombs they throw at you.
When one of the baboons throws a Watermelon Fuse Bomb, move quickly to grab it, then jump up and toss the bomb into the baboon at the top of the pendulum.
During this phase, the new members of Ba-Boom also utilize a modified swing attack. In addition to sweeping through the area, the baboons toss bombs to the ground. Use the same basic tactics as during the battle’s first phase, but take care to get clear of each bomb before it detonates.
Jump over the baboons when they swing upright, and bop them when they swing upside down. Bopping the specters simply resets them, but bopping the more tangible baboon will force the enemies to change their tactics and bring you one step closer to completing this encounter.
The second time the baboons combine to form a pendulum, they litter the area with red bombs. Avoid the bombs as they fall, then find a safe spot to stand until they detonate. Repeat the process until one of the enemies throws a Watermelon Fuse Bomb to the ground, then hurry over, grab the green bomb, and throw it into the baboon at the top of the pendulum.
Hit the last original member of Ba-Boom, the Boisterous with three successful attacks to trigger the battle’s finale. Follow the on-screen prompts to end the encounter with a punishing melee combo. After you complete stage 3-Boss: Triple Trouble, you automatically travel to stage 4-1: Deep Keep.
