Part 30

Supermassive Galaxy - Big Wigglers Speed Run: Finish the level with 2:30 on the timer. Follow the regular walkthrough, avoiding time-consuming detours. Having 20+ seconds before reaching the Wigglers ensures success. The Star is atop the pole at the end.

Flipsville Galaxy - Purple Coin Spin Speed Run: Collect all purple coins underground within 2:30. Gather coins in the initial area, then drill right, up, left, and up. Continue drilling right, left twice, and down twice to return to the start. The Star appears in the middle area with the timer off. Use wall jumps and spin/drills before gravity shifts to reach coins. Drill on white surfaces to avoid falling through.

Chompworks Galaxy - Cosmic Clones in the Chompworks: Lead the Golden Chomp while clones follow. They appear after the first platform. Long jump to the start and follow the regular walkthrough. Avoid stopping or backtracking; create new paths to save time as clones mimic your movements.

Starshine Beach Galaxy - Purple Coin Beach Dash: Collect 100 coins in 35 seconds using the Dash Pepper. Run through coin strings, making slight left/right adjustments to grab pairs or trios. Refresh the Dash Pepper as needed. The Star appears at the end of the track once 100 coins are collected.

Bowser's Gravity Gauntlet - Gravity Star Speed Run: Collect clocks throughout the level, starting with 30 seconds. Grab the clock on the left crate, then the Life Mushroom in the bottom right of the rotating platform. Collect another clock, then head right along a thin path and get the clock above the block. Collect the clock on the right, avoiding fireballs. Wall jump for a clock, then head to the underwater area for clocks near fish. Head right and down, avoiding the wall crusher, and grab a clock on the left, then a 1-Up below. Quickly head down and left for another clock. Drop down, go left for a clock. On the rotating circle platform, get the clock on the right, then jump to the next platform. Jump/spin for a clock, then head left to the top and jump/spin for the Star.

Slipsand Galaxy - Squizzard's Daredevil Run: Fight Squizzard with only 1 health point. The fight is identical to the regular star.

Shiverburn Galaxy - Octo-Army Icy Rainbow Romp: Knock out 30 Octoroks in 50 seconds. Use the Launch Star (losing ~5 seconds) and grab the Rainbow Star. Skate to defeat all Octoroks, refreshing the Rainbow Star before it runs out.

Bowser Jr.'s Boom Bunker - Boomsday Machine Daredevil Run: Complete the level with 1 health point. Follow the regular walkthrough until the second cannon; aim for the square target. Avoid purple goo and ride the silver platform, then a moving platform, tilting to avoid goo. Hit the Checkpoint Flag, get the cloud flower, and use the Launch Star to reach the Boomsday Machine boss. Use the same strategies as the regular fight. Fight the Boomsday Machine again with 1 HP, using the same strategies.

Flash Black Galaxy - Dark Octo-Army Romp: Defeat 30 Octoroks in 80 seconds. Bounce on enemies consecutively and be aware of the flashing light path. If you miss a stomp, spin instead to save time. The timer stops after the 30th Octorok; reach the Star on the last platform in the back middle area.

Clockwork Ruins Galaxy - The Adventure of the Purple Coins: Collect 100 purple coins in 5 minutes. Collect 9 coins before the first mechanism, 23 after the first, 37 after the second. The next mechanism yields 65, and the following Widdle shows 73. The final mechanism provides the remaining coins. The timer stops, and you must ride the end platform to its peak rotation to get the Star.

Throwback Galaxy - Whomp Silver Star Speed Run: Repeat the earlier silver star level within 2:00. Follow the normal walkthrough, avoiding backtracking or distractions. The timer stops at the 5th silver star, and you collect the Star.
