Hydroe bramble

Hydroe brambles are green thorny stalks serving as an extension of the Berserk Leech Hydroe, and as obstacles that pose a passive threat since they kill any Pikmin and hurt leaders that touch them. Each one can have different behaviors, between staying stationary, advancing and stopping, or moving in and out of place, and each one can also move in a straight line or a curvy pattern.

In Pikmin Eco
Hydroe brambles appear in Pikmin Eco as an as additional obstacle at Bounty Canopy after finishing story mode. Although they don't actively attack, touching any bramble is enough to kill any Pikmin and damage leaders, making them worth avoiding. Despite this, they can still be scanned and are included in the Piklopedia.
