You'll start noticing tougher enemies around here, including some of Bowser's crew. They're good for racking up Star Points! Head left until you see a red X on the ground. Use your Spring Jump, then shimmy left and drop down to find a chest. Inside, you'll snag a Flower Saver P badge. Now, Spring Jump back up and head right to find a pipe going down.

More of Bowser's soldiers are in this next room. Keep going right.

Here, use your Ultra Hammer on that gray block. Hop on the elevator and grab the chest – it's got an FP Plus badge! Now, hit the big "!" blocks by Spin Jumping on them. This will reveal two pipes. The left one leads to Poshley Heights, and the right one goes to Keelhaul Key. For now, let's head to the sewer's main shopping area.

Do your trading with Dazzle, then take the elevator up to the Underground Shop. Head towards the background, line yourself up with the pipe, and Spring Jump. Shimmy right onto the shop's roof, then onto Merluvlee's roof. From there, jump onto the pillar near Dazzle – there's a Shine Sprite on top! Grab it, then go two rooms to the right, to the area where you fought the Blooper before Chapter 1.

Line yourself up with the pipe here. Shimmy all the way right and drop onto a platform with another pipe. You might remember this spot from when you used Boat Mode after Chapter 5. Use this pipe to get to the background. Enter the house there to find a Star Piece. Leave, use the pipe again, and Spring Jump onto the pipe. Shimmy left and drop back to where you started. Now, line yourself up with the pipe on the left side. Spring Jump and shimmy onto the platform to your left. Bring out Bobbery and have him explode near the wall. This opens up a hole leading to the room on the left. Go through it, and you'll pop out onto a ledge. Open the chest here to get the Defend Plus P badge. Once you're done, it's time to head to the Thousand-Year Door.

After the usual spectacle, the location of the final Crystal Star is revealed: the Moon! You'll end up back at Frankly's place.

Rogueport

Frankly confirms what you probably already figured out – the Crystal Star is on the Moon. He's not sure how to get there, so he asks for some time to research. Feel free to do some Troubles, promote your partners, or tackle the Pit of 100 Trials for a bit. Just give him about ten minutes.

When you return, Frankly will have a plan: you need to be shot there! Apparently, there's a giant cannon in Fahr Outpost that can do the job. To access the pipe leading to it, you'll need the Ultra Hammer, which you already have. If you broke the gray block under west Rogueport, you know where the pipe is. If not, head to the sewers through the grate in west Rogueport, break the gray block on the left ledge, and use the pipe inside.
