Star #2

Just past the stamp is a cracked wall. Step into a searchlight to be swarmed by Cat Suit Bullet Bills. Lead one into the cracked wall to blow it away, revealing a mystery box.

World 6-2: Spooky Seasick Wreck

Star #1

When you come to the pair of Bullies, take them both out by knocking them off of the edge of the course. You'll get a star for slaying them both.

Stamp: Moneybag

You could propel to the roof and finish the course early now. Instead, collect all the keys to unlock the warp box and reach a hall with several Spikes.

You can then jump to a cloud platform where the stamp awaits.

Take him out before time runs out to earn star.

World 6-4: Deep Jungle Drift

Stamp: Cat Suit Toad

When your reach the first island, leave by the upper path. You'll probably need a Cat Suit to get there. Swing across the poison via the trapeze to land on a blue platform where the stamp sits.

Star #1

If you take the lower path, you'll find this inside an isolated clear pipe. Just make sure the raft has moved far enough ahead that the pipe won't spit you out right into the poison!

Star #2

Just past the checkpoint is a hollow green star. You'll need a Cat Suit to scramble to the upper level to reach it and spawn eight green coins. Grab them before time runs out to earn a star.

Star #3

The last star in the level is very tricky to grab. Jump when the wind is whipping, and it carries you over the star. Jump when the wind is clear, and you'll fall to your death. A few wisps appear in the pit just before the wind kicks up - jump when you see them to grab the star and be saved by the wind.

World 6-6: Bullet Bill Base

Star #1

Using the Cat Suit, you can make your way to very top of the first base. There's a star waiting there.

Star #2

Stamp: Stunned Goomba

The stamp is on the final platform overlooking the flagpole. You simply have to jump onto the row of bricks, then jump up to the stamps. If you happen to break the bricks, you can still reach the stamp with a spin jump from the raised ledge.

Stamp: Fuzzy

This is found early in the level. When you reach the first horizontal retracting platform, you'll spot it inside the dip.

Star #1

You have ten seconds to complete each room's challenge. For the first, quickly chuck a baseball down the slope. The ball rolling into the star counts as picking it up.

Star #2

Immediately jump once in the second room to flip the panel to red. Now grab a baseball and jump. As the panel flips to blue, chuck the ball into the star.

Star #3

In room three, grab a baseball and use the jump pad. Move forward while doing this to practically dunk the basketball into the switch on the wall, summoning a star.

Star #4

The fourth room is full of Para-Biddybudds. Use baseballs to hit the POW Blocks and clear them out. This spawns a star.

When you reach the two platforms with rotating flames, move to the second question mark block. If you ground pound this, it will become a tower of bricks, carrying you up to a previously unseen stamp.

World 7-5: Trick Trap Tower

Star #1

You'll find the first star very early in the level, but you'll need a Cat Suit. After riding the second set of yellow platforms, leap to the left ledge. Scramble up here to find the star.

Star #2

World 7-Special: Captain Toad Gets Thwomped

Star #1

This level is all about timing. The first star is an alcove behind the first Thwomp. Slip back there when it's airborne to grab it.

Star #2

When you ride a Thwomp to the next floor, look for this in the corner.

Star #3

On the next level up, slide along the conveyor belt after the Bullet Bills have passed, and grab this in the corner.

Star #2

Just beyond is a cannon firing soccer ball bombs. Kick one into the big bricks to reveal s switch - don't press it yet! First, use a Cat Suit to scramble up the walkway before you lower it; there's a star up there.

Stamp: Boomerang Mario

Now move to the alcove with the switch. Wall jump upwards to find a high altitude stamp.

Star #3

When you reach the platform covered in Parabones, turn left. You'll have to traverse those spiked platforms to reach the end of the level anyway, but there's a star to be had. You'll have to grab it from the falling platform, then jump back to the spiked one before falling. You can do it!

World 8-2: Plessie's Dune Downhill

Star #1

The first star is hovering above the first part of the level. Bounce off of your enemies' heads to reach it.

Star #2

After the big drop, continue through the snaking path. When you see a group of Para-Biddybuds, leap over them to snatch the star.

World 8-3: Cookie Cogworks

Star #1

After passing the Giant Piranha Plant, hop onto the next cog. Turn left and hop onto the cog behind you, then ride it up to spot the first star. It is possible to reach this with a jump, but a throw from the Boomerang Suit makes the job much easier.

Stamp: Boomerang Toad

Just after the clear pipe is a line of Spiny Ant Troopers. Grab the Boomerang Flower in their lineup, then take them out. Drop into the hole they were patrolling to grab the stamp.

Star #2

Right after, you'll encounter two patrols of Spiny Ant Troopers. Use your Boomerang Suit to clear them out again, then drop through the holes they were guarding. Hop into the mystery box down here to enter a challenging secret room. Inside, you'll be atop a spinning wheel.

World 8-Train: The Bowser Express

Star #1

This is atop the very first train car you see. Hit the wide question mark block, then jump in the middle to hit an invisible block. Use this to reach the star.

Star #2

Shortly after, you'll spot a hollow green star above some pendulous spikes. Hit it to spawn eight green coins; grab them before they disappear to earn a star.

Stamp: Conkdor

When you reach the tall train car, you'll see the stamp on the roof. Don't worry about getting up there right now. Instead, head through the door into the train car. Ground pound the right question mark block to generate bricks that carry you right up to the stamp.

When you reach the front of the train, drop down to the lower ledge. Take out the Fire Bro. to nab the star behind him.

World 8-4: Footlight Lane

Star #1

As you cross the section with rolling spikes, you'll approach a hollow green star. Hit it to spawn eight green coins on the spikes' path. Grab them before time runs out to earn a star.

Stamp: Bullet Bill

You'll come to a platform targeted by Cat Suit Bullet Bills. Leap to the right to land on an invisible platform. Up the invisible steps here is the stamp.

Star #3

While navigating the same walkway with the Cat Suit Bullet Bills, look for a narrow path to the left. This leads to a mystery box; hop inside. In here, you'll have ten seconds to reach the star. The walkway is pretty broad, so quickly leap atop the Thwomp to reach your prize.
