In Pikmin E: The Next Adventure
In Pikmin E: The Next Adventure, the Boulderous Biper serves as the boss of the Miraculous Mine. It is huge, around the size of the Vehemoth Phosbat, and is covered with a shell made of rock. Despite its unique appearance, it behaves identically to a normal Biper.

In Pikmin: Decayed Leaf
The Boulderous Biper is a DLC boss in Pikmin: Decayed Leaf. The creature resembles a typical Biper, but is quite large, around the size of a Vehemoth Phosbat. Numerous large brown stones cover its entire body except for its eye, legs, and head spike. When encountered, the boss starts the fight by falling from above and slamming into the ground.

The Boulderous Biper can skewer up to 25 Pikmin to eat them. In addition, it can charge the group by rolling in one direction, crushing any Pikmin caught in the way of the attack. When it slams into a wall, it will lose some rocks and be stunned for a few seconds, and three Bipers will fall from the sky to aid it. Now is the chance to attack the Boulderous Biper. The more the Boulderous Biper is damaged, the more rocks it loses. After about three-fourths of its health is depleted, the Biper will lose all of its rock armor. It will also lose its charge attack, making it very vulnerable. At this point, it looks just like a very large Biper.
