In Pikmin 4 (BallsAngus version)
The Diamond Long Legs is an arachnorb miniboss in Pikmin 4 (BallsAngus version). It is the rarest arachnorb encountered, appearing only once in Silver Lake, and in two caves, Chaotic Cove and Spider's Web. At Silver Lake it is located in a snowy arena to the east of the landing site, where there are gems arranged into the shape of a web. Rock Pikmin are recommended to fight the creature with as it has a covering made of diamond. When defeated there, it drops the Snow Parka.

The Diamond Long Legs can not be fought without using Rock Pikmin, which are immune to being crushed and stabbed, only making them more useful against the creature. To defeat it, simply throw Rock Pikmin at its protected core until its crystal coating shatters and then hit the main body to inflict damage to the boss. Whenever its armor is broken, shards of it will come crashing down to the ground, impaling any Pikmin unfortunate enough to be under them as they land. The coating will eventually reform and must be broken again.

In Pikmin: Decayed Leaf
The Dropperfoot Legs is a boss arachnorb in Pikmin: Decayed Leaf. This insect resembles many other arachnorbs, but its main abdomen is covered in a shell of hard, rigid crystal. Its slender legs are made of a black organic material, and breaking the calcified crystal reveals the creature's soft, purple, pink-spotted exterior. Upon entering its arena, only a large ball of crystal resting on the ground is visible in it. When approached, however, four legs will immediately and violently erupt from it and lift the crystal off of the ground, the arachnorb revealing its true form.

The Dropperfoot Legs attacks by slamming its feet onto the ground in a set pattern. After each foot stomps twice, it will perform a slight hop and extend its legs upwards so as to slam its body into the ground before its four feet can, and then return to stomping about. Any Pikmin caught in this attack will be killed instantly, while Rock Pikmin will be returned to sprout form and have to be plucked. To attack this creature, throw Rock Pikmin at its shell. Alternatively, although a bit ineffective, Dart Pikmin can also pierce through the shell. Breaking off a section of its shell will reveal a portion of its skin, and breaking off five sections will reveal the entire body. Afterward, the arachnorb will start to stomp around at twice its usual speed and shake off any Pikmin that start to do serious damage to it. When it slams its abdomen into the ground at this point, any Pikmin in the way will simply be buried. Once defeated, the abdomen will open up and empty out the treasure, and the arachnorb will overheat and melt away.

In Pikmin IV
In Pikmin IV, the Diamond Long Legs is a somewhat common arachnorb species. It moves incredibly slowly, and much like in Pikmin 4 (BallsAngus version), hitting its crystal armor until it breaks will reveal its vulnerable main body but allow the creature to move much faster. Breaking the bits of crystal on the boss's joints will deal a fair bit of damage to it. When defeated, the Diamond Long Legs will roar, stiffen up, drop whatever it was holding, and then completely shatter. The crystal shards will knock down Pikmin and leaders they land on but are otherwise harmless.

In Pikmin: Treacherous Treasures
Diamond Long Legs is an arachnorb miniboss in Pikmin: Treacherous Treasures. It can only attack by stomping slowly about and crushing Pikmin under its large, clawed feet. Its metallic blue torso is protected by a large diamond, much like how its joints are protected by crystal beads, necessitating the use of Rock Pikmin to defeat the creature. Once its diamond or at least some of its beads are destroyed, the Diamond Long Legs moves much faster; furthermore, the creature sustains damage for every destroyed bead, and when its diamond is destroyed, it suspends its torso high enough off the ground that only thrown Yellow Pikmin can reach it. When defeated, it disintegrates into sparkling dust, and the crystal fragments can be retrieved for Pokos. Although extremely challenging, it is possible to defeat a Diamond Long Legs without destroying its diamond shell by simply targeting the beads around its joints; destroying them all will kill the creature, leaving its diamond intact and yielding many more Pokos than its fragments.
