Editing Berserk Leech Hydroe

When its health is on the last half, there will be some changes to its attacks. When it shoots balls of poison when its body is in reach, it will actually fire five of them, one by one. The first ball will land directly below the claw, the second will land just after the edge of the arena, the third will land midway between the edge of the arena and the point below the claw, the fourth will land far away off the arena, and the fifth will land midway between the first and the third. When it goes to the background to fire beams, it will fire a second one after the first, and they will also be faster than the one it shoots when over half health. When it chomps down at the floor, it will do so three times in a row, slightly deviating the position each time. When it shoots beams while on the background, it will shoot two now instead of one. They also approach the foreground faster.

As soon as it starts, run under the creature. Only do this if your Pikmin are flowered, otherwise they will be too slow to catch up and will likely get hit by some poison balls. If they are bud or leaf, then wait until the first three balls of poison are fired before running under the boss's body. The first three balls it fires will land roughly below it, moving slightly forward, so keep this in mind when waiting for the first set of balls to finish. Once under the creature, throw Pikmin at its body. You can throw just one, or as many as you like, since it won't make a difference. After the gust of wind, its claw will hover above you. Wait one full second, and then start moving in the direction its body used to be in. This should give you enough space to run and avoid the claw when it strikes down. Then, when it's dangling, throw Pikmin at it. As soon as the boss shakes the Pikmin off, quickly run to the end of the arena in the same side the boss is facing, i.e. the side opposite from the one its body used to be in. As long as you hug the boundary, and force your Pikmin to hug it with you (keep holding the direction and use the whistle), you will avoid the poison balls. If you can't make it to the edge in time, then pay attention to the boss as it spits balls, and stand directly under the position where it spit a couple of balls. Any of these positions will be safe for the duration of the attack. When the Berserk Leech Hydroe goes to the background, for the beam attack to start, and simply dodge to the side once it begins.

After its health reaches the second half, some of its attacks will change. When it shoots balls of poison with its body in reach, it will actually shoot five, one at a time. Hugging the edge of the arena is safe, as is simply being under the creature. But to get under it may be difficult. The best way is to wait for the first poison ball to land, which will land directly below the claw, and then run under the boss. If you're having trouble with that, then hug the edge of the arena to avoid all attacks, and then continue to walk in the direction of the edge even after the creature flies off. When it flies in from the same side you're holding in, you will be fighting against the gust of wind and will easily get under the boss before it even shoots the first ball. When it clamps its claw at the floor, it will do it three times in a row slightly deviating the position each time. So keep a bit more distance than normal, and wait for the third chomp before throwing Pikmin. When it goes to the background to shot beams, start by giving yourself room to run, and look at the floor below the boss. As soon as you see the beam on the floor in the background, run in the direction you chose. Remember to repeat for the second beam. It's best to use this strategy instead of looking at the boss's claw, because it won't start sending the laser until after some seconds of charging up, and the time it takes to charge up between the two shots is not the same.
