Bouncing Down Cake Lane

After arriving, take a train to the right and spin into the Star Launcher to reach a platform beneath two large cakes. Grab the Spring Mushroom and wall jump up the cakes.

At the top, head right and jump onto a conveyor belt with tall chocolate walls. Use Springy jumps to get over the walls while progressing along the belt without falling.

Jump from the chocolate conveyor belt onto the Spinning Cake. Use your Spring form to jump around cutlery obstacles and missing wedges to get behind a Chocolate wall. Find a Sling Star to reach an ice cream cone.

From the ice cream cone tip, make your way up. You can jump from popsicle stick to popsicle stick, or wall jump up the first two and then jump across the tops. Jump to the spinning lollipops, avoiding the Ring Beamer's lasers.

Jump from the lollipop to an icy platform, being careful not to slide off. Traverse a series of thin ice platforms while avoiding electrogoombas. Enter the orange cannon to be blasted into a Star Launcher that leads to the big birthday cake.

On the big birthday cake, spin attack the flames of all candles to blow them out. A Star Launcher will spawn at the top. Collect Star Bits and coins if needed before using the Star Launcher.

The Undergrunt Gunner boss fight requires using a Spring Mushroom to jump onto the Gunner's machine. Avoid flame shooters and flaming cannonballs. Groundpound the glass casing three times to defeat him. After the second hit, he attacks faster. A Power Star spawns at the top of the balloon jar upon his defeat.
