How to Reach Below-Grade Discotheque

At the Back of the Sandcastle

From the starting base location, go east and traverse the large sandcastle, eventually reaching the middle area where you can place your base after defeating a large enemy there. The Below-Grade Discotheque's cave is found south of that middle area.

Below-Grade Discotheque Bosses and Enemies

Bosses

Groovy Long Legs

Make sure to fight the boss while riding Oatchi as it makes it easier for you to gather the Pikmin after attacking and easily avoid the purple smoke attack as any Pikmin affected by the smoke cannot be called back and may be trampled in the process. Groovy Long Legs will start shooting a purple smoke once you attack its weak point.

Once Groovy Long Legs' health becomes low, it will start to glow red and move faster. Do not attack the boss while in this state as there is a risk that your Pikmin may get trampled as it stomps around the arena. Wait for the boss to turn blue before attacking.

Below-Grade Discotheque Tips and Strategies
Bring Red Pikmin and Yellow Pikmin Recruit Winged Pikmin

Bring Red Pikmin and Yellow Pikmin

Pikmin to Bring
Red Pikmin 30 or 40	Yellow Pikmin 20 or more

Below-Grade Discotheque has a lot of fire obstacles, electric gates, and high platforms so be sure to bring a lot of Red Pikmin and Yellow Pikmin with you.

The boss, Groovy Long Legs, has high health so having Red Pikmin is recommended due to its high attack power.
