Diamond Long Legs

The Diamond Long Legs is a mini-boss encountered in Pikmin 4 (Wii U). It is the rarest arachnorb in the game, only appearing once in Silver Lake. It is located in a snowy arena to the east of the landing site. There are gems that are arranged into a shape of a web. Rock Pikmin are recommended, however, the shards could sill penetrate through the pikmin, since it is diamond. It has a covering made of diamond, which is why rock pikmin are advised. When defeated, it drops the Snow Parka upgrade.

''This species of arachnorb uses gems or hard minerals as a defense mechanism. It uses the minerals as armor to protect itself from enemies. When it's armor is removed, it is vulnerable to attacks.''

Strategy
Bringing rock and brown pikmin are recommended for this boss. Toss rock pikmin at its abdomen, until it has been exposed. Then use the brown pikmin to finish it off.

Pikmin 10
In this game, the Diamond Long Legs is a bit more common. It will be pretty slow, going as fast as the Raging Long Legs not raging. Using Rock Pikmin to break the main diamond(50 direct hits) you can now attack its body. Be aware that it will go faster now, just slightly faster than Beady Long Legs. Breaking the crystal covering its joints(10 direct hits) will make it lose a quarter of its health. When killed, it will roar, stiffen up, and it's body will shatter like crystal, as well as any not destroyed joints shattering as well.
