Brown Pikmin

A Brown Pikmin is a type of pikmin. It's tan, but is covered with brown silk. The pikmin's silk is explosionproof. However, its silk is explosionproof, making it good for strong explosion enemies such as the Gatling Groink and the Man-at-Legs. It is from the Supernova Candypop Bud. It latches on enemies via silk, so it will swoop into the enemy once shaken off.

In Pikmin: Connection of the Worlds
Brown Pikmin appear in Pikmin: Connection of the Worlds, but are very different than the type aforementioned above. They are resistant to earth in place of explosions (Orange Pikmin are resistant), and have the ability to dig through soft earth because they have sharp claws on their fingertips. This is useful for reaching normally cut-off areas, but sometimes the tunnels may split and wind throughout the area, creating shortcuts. Unfortunately, sometimes the tunnel may end in a body of water, allowing only Blue (and Cyan) Pikmin to pass through. They will stop digging when a crack appears (this is for every tunnel) then the captain has to punch it a few times. Aside from that, they are found in the Dirty Candypop Bud. and are found at the Ancient Valley.

They have slit-eyes that help them see in thick sandstorms. You need Green Pikmin to get to their candypop bud, which, by the way, is called the Dirty Candypop Bud
