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 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.
