Battlerock Barrage

First things first, you need to grab all 5 of the blue Star Pieces. They're scattered on these little flying saucers, some on top, some underneath. Once you've got them all, you can use the Pull Stars to get yourself to the Launch Star, which will send you to the next area.

You'll land on a small saucer with a purple jump spring. Use it to bounce up to the saucer above. Head to the top of that one and you'll find a blue screw. Give it a spin by pressing Y or shaking the Right Joy-Con. This activates the saucer and kicks off the main part of the level!

Now, you're on a flying saucer and cannonballs are going to start flying at you. You can move to the underside of the saucer to dodge them, but watch out for the electric balls spinning around the edge. You'll also need to quickly move between sides of the saucer if electric fences get in your way. It's mostly about quick reactions – sometimes you'll need to drop to the bottom and then immediately dash to the side to avoid a blast.

Once the flying saucer stops, you'll arrive at another saucer with a trapped Power Star. Nearby, there's a saucer with 4 cages. To the right of these saucers are two Bullet Bill shooters. You need to get the Bullet Bills to target you – they'll lock on like missiles. Your job is to guide them to smash into the cages.

Start by guiding Bullet Bills to crash into the four smaller cages first. These are mostly filled with Star Bits, but clearing them out gives you a clear path.

Finally, guide a Bullet Bill towards the cage on the main saucer. This will break it open, freeing the Power Star and completing the level!
