Stage 2-3

Grab the Wheel ability at the start and drive up the ramp to find a door.

Enter the next room and press Ⓑ to Dash.

Ride the first 3D Warpstar and grab Sticker #1 upon landing.

Take another 3D Warpstar, Dash over spikes and through star blocks to an alcove containing the Rare Sticker for this level.

Enter the door to the next room, which contains Spark and Parasol abilities, and food from Bandanna Waddle Dee.

Prepare to fight the mini-boss, Miasmoros.

Defeat Miasmoros. Its attacks include Small Hop, Big Hop, Forward Dash, Poison Spit (1 & 2), Poison Chaser (1 & 2), Poison Stream (1 & 2), and Junk Flinger.

Ingest Miasmoros to obtain the Poison copy ability.

Head through the door to a room with a red switch and a monitor.

Press the red switch to reveal 3 symbols dictating the treasure path: HEART > SPADE > DIAMOND.

Take the HEART path, which may contain a Toxioad enemy providing the Poison ability if not obtained earlier.

The door at the end of the correct path leads to a room with four pieces of food and a treasure chest containing Code Cube #1.

Proceed to the next room and enter the Robobot Armor in the dock.

Scan a nearby Rocky enemy to activate Stone Mode.

Use Stone Mode to push trucks into pits as you progress upwards.

At the top, use Earth Shaker (⇩ + Ⓑ in midair) to break gray blocks behind a truck.

Push the truck to keep the red switch pressed down, then jump up to collect Code Cube #2.

To the right, before the next door, push a large truck right to reveal stairs leading down to a dock with Sticker #2.

Grab Sticker #2, exit the Robobot Armor, and proceed to the next room.

Follow the path right and up to the fourth energy field.

Look up to find a switch hanging from a box above; grab it to reveal Code Cube #3.

Collect Code Cube #3 and drop down to the energy field down and to the right.

In a small pit, find Sticker #3 (Note: Source text incorrectly states Sticker #2 is here, but it was found earlier. Assuming this is Sticker #3 based on total count).

Make your way right and exit the stage.
