The Arachnode is a spider-like creature in Pikmin 3. When undisturbed, they'll take on a cocoon-like appearance, but once a Pikmin or leader is caught in its web, it will reveal its true form and try to attack them. Their webs act as the primary hazard for Winged Pikmin. When Winged Pikmin are carrying anything back to the Onion, and an Arachnode and its web are in the way, the Winged Pikmin will get stuck, putting them at risk of being devoured.
