Follow this guide to defeat Megaleg and obtain the second Grand Star in Bowser Jr.'s Robot Reactor Galaxy in Super Mario 3D All-Stars. Learn boss strategies and tips.
This page is dedicated to the Megaleg’s Moon Grand Star in Bowser Jr.’s Robot Reactor Galaxy. This galaxy is located in the Terrace dome and is the last galaxy to be unlocked in the dome, requiring 8 stars. It is here where you obtain the second Grand Star in the game.
When you land on the starting planet, take the opportunity to collect all the star bits, coins, and the 1-Up Mushroom. The planet is relatively small, so this shouldn’t take too long. To destroy the glass containers on the planet, you need to have a Bullet Bill lock on and chase you, then have it break the casing on impact. This is how you will get access to the warp star and head to Megaleg.
