Complete walkthrough for Part 20 of Super Mario Galaxy 2, covering Battle Belt Galaxy and Bowser's Fortified Fortress.
Walkthrough
- 1At the moving platforms, get the Cloud Flower and drop below the 2nd platform to collect a star (1). Use a cloud to save yourself.
- 2Wait until it is clear to reach the upper side. Pass the Thwomp and stand atop the crates, then long jump towards the stationary clouds with a star (2) and a Cloud Flower to refresh.
- 3Long jump further back to the main area and around to two crates that reveal a Sling Star.
- 4Backflip in that area and use 1-2 clouds to reach a row of clouds.
- 5Long jump to a star (3) in between two rows of clouds.
- 6Head to the top of the fortress around the left side with the Piranha and rotating platforms to refresh your clouds on top and backflip.
- 7Use about 2 clouds to reach the last star (4) atop the Bowser image on the ground. The star will appear here.
- 8Head to Battle Belt Galaxy and start Mini-Planet Mega-Run. Defeat the Goomba to start and use the Sling Star.
- 9Spin at the fiery rocks and long jump over a lava hole in the lower right side, then take the new Sling Star.
- 10Use the Fire Flower to destroy the 3 spiked balls, then use the Sling Star and fire at the crabs.
- 11Find a 1-Up on the sandy planet and use the Sling Star to reach the Starshroom ship.
- 12Hit the Checkpoint (an auto-save point you restart from on death) Flag (checkpoint) on the bottom and use the Sling Star.
- 13Spin at the pumpkin Goombas, then stomp/spin each one to get a key that frees a pipe on top.
- 14Use the pipe and swim down to the Koopa shell at the bottom. The light coming from it will defeat each Boo, so just aim at each one.
- 15Use the Sling Star to return back, and then use the Sling Star at the bottom.
- 16Use the Luma Shop if you want at the bottom side, then use the 2nd Checkpoint Flag and the Sling Star on top.
- 17On the icy planet, spin into the icy rocks, then use the Sling Star.
- 18Pound the ground near the Monty Moles, then stomp/spin each one.
- 19Use the key to reach the pipe. Defeat the 3 enemies when their spikes are facing down. One is safe to stomp in blue/down gravity and two in red/up gravity.
- 20Once finished, wait for red/up gravity to reach the pipe, then use the Sling Star on the opposite side.
- 21Spin at the green bulbs to knock out each Silver Chomp and use the key to release the Star.
- 22To get Secret Star #1- Snacktime For Gobblegut, re-enter Mini-Planet Mega-Run and collect at least 20 coins from the enemies and a few lying around.
- 23On the icy planet just after the 2nd Checkpoint Flag, feed the Hungry Luma at left 30 coins to use its Launch Star. You'll reach a new version of the miniboss Gobblegut.
- 24Use the same strategies to fight it as earlier, but this time, you can't touch an inch of the dragon as it's entirely on fire. Watch out for the lava pools that appear on the planet after the 2nd phase. You win the Star for defeating it.
- 25Head to Bowser's Galaxy Generator and start Bowser's Fortified Fortress. Head to the far left to the pole and climb it for a Life Mushroom at the top.
- 26Backtrack a bit and head up, timing your jumps between the fireballs and rotating firebars.
- 27Use the Luma's Launch Star, then defeat the 3 Hammer Brothers.
- 28Spin at the Floaty Fluff ahead and ride a seedling over the lava, avoiding the fireballs being shot out. Spin to gain altitude (a max. of 3 times).
- 29Drop at the end to the platform and grab the Spin Drill, then drill in the soil patch.
- 30Head up and hit the Checkpoint Flag.
- 31Wait for the Banzai Bill to pass, then duck to the left to avoid it. Head up and quickly drill before it returns, then head right, avoiding the next one and stand in the left corner of the fence.
- 32Duck left to avoid the next one, then on the right side. Drill there to get a 1-Up, then return and drill at the spot in front of the chute.
- 33Use the Launch Star to continue.
- 34Hit the 2nd Checkpoint Flag and wait for the moving platform to arise from the lava.
- 35Jump right between the fireballs to reach the Cloud Flower.
- 36Drop at the right to get the Life Mushroom and use a cloud to save yourself. Refresh, then backflip and use clouds, avoiding the Bullet Bills.
- 37Refresh, then get the ? coin, dropping into a row of coins and then use a cloud to ride the vent's wind right.
- 38Refresh again and head up more, refreshing again between the Bullet Bills.
- 39Backflip and use a cloud all the way, then refresh again and head up left to the Luma.
- 40Use its Launch Star to move on.
- 41Hit the 3rd Checkpoint Flag and head up the bridge, defeating the Magikoopa.
- 42Head right on the tipsy platform and get Yoshi.
- 43Backtrack left and use the swinging flowers.
- 44Head left, swinging quickly over the lava where plumes emerge.
- 45The 1-Up in back is probably not worth it, but if you defeat the Hammer Bro and swing left to it, it's yours.
- 46Head left and defeat the 2 Boomerang Bros. to open the doors ahead.
- 47If you lose Yoshi, get it again at left in the nest.
- 48Use the Dash Pepper and head right, then left, avoiding the towers, then straight, slightly left, and back into the middle.
- 49Use the Sling Star, then ride the purple platform ahead getting the Life Mushroom, then head right over the lava and firebars.
- 50Jump/float left, then back right to avoid the lava monsters.
- 51Swing on the flowers to get the Comet Medal, then jump/float back onto the purple platform.
- 52Wait for the lava monster to appear, then use the blimp fruit to float around it and get back on the purple platform.
- 53Ride straight up to the last Checkpoint Flag.
- 54Dismount Yoshi (if you still have him) and climb the pole up. A Life Mushroom sits at left if you need to refresh (it will be a 1-Up if you have a 6).
- 55Pound the golden ball 3x to break the stone locks and be pulled through the door to the Bowser fight.
