Ba-Boom

Ba-Boom, the Boisterous is the third boss in the game Donkey Kong Country: Tropical Freeze and its Nintendo Switch port of the same name. It is a trio of baboon brothers serving as the bosses of Bright Savannah, appearing in the level Triple Trouble. Before the battle, the Kongs notice a Banana Bunch in the air by a wooden pole. As they try to grab it, a baboon slyly snatches the bunch. It then splits into the three members of Ba-Boom, all of whom promptly mock the Kongs, angering them.

Physical description
Ba-Boom consists of a trio of s, though their bright cheeks make them more closely resemble s (possibly a reference to the fact that mandrills were formerly classified as baboons). Aside from their cheeks, their faces resemble a long version of Donkey Kong's, and they also have messy hair. They each wear a Viking helmet with the Snowmad insignia on it, as well as bracelets on their arms and legs. The three look exactly alike except for the color of their cheeks and bracelets, being blue, teal and red. The members of Ba-Boom are the only primates in the Donkey Kong franchise to have four fingers and toes since the GameCube era.

Attacks
The three monkeys move quickly, often relying on his speed to attack. The Ba-Boom brothers attack by swinging a rope, and swinging a hammer. They can all perform a rolling attack, though they end up getting dizzy and vulnerable at the end of it. They also throw Watermelon Fuse Bombs, which can be spiky or green; the green watermelons can be thrown back at them. A baboon can also call his siblings to his side if they are not defeated. When two of the brothers are defeated, the remaining baboon will summon weaker specters of them, and repeat the aforementioned patterns. The baboon and these ghosts also swing back and forth in a chain formation while tossing bombs and the specter at the bottom of the chain sometimes swinging a hammer.

Combat
To defeat Ba-Boom, the Kongs will have to damage the brothers, either by jumping on them, or by throwing their Watermelon Fuse Bombs back at them. However, the Kongs can only jump on their rear ends, as their helmets will render jump attacks on the head useless. However, this can be mitigated by using Cranky Kong's Cane Bounce. They are more vulnerable when on the ground, and they can be rolled into.

Each brother can only take up to three hits, and as they take damage, their fur color becomes lighter. When one Ba-Boom member is defeated, however, the remaining members will fully heal themselves before beginning the next phase.

Trivia

 * While the members of Ba-Boom are referred to as brothers in both the Japanese text and the Prima Games guide, the first baboon appears to use in order to create or summon two of them before the boss fight, as evident by his usage of hand seal movements.
 * When a baboon performs a rolling attack, the animation and sound effect are similar to Sonic the Hedgehog's Spin Dash.
 * Given how one of the baboons lured Donkey Kong into a trap with a Banana Bunch, this makes Ba-Boom the only other boss in the game (besides Lord Fredrik) to have seemingly known about Donkey Kong. This idea is also hinted at by the numerous prohibition signs bearing Donkey Kong's tie that can be seen in this world.
