Blooper Barrage (level)
From the Super Mario Wiki
Blooper Barrage is the seventy-fourth course in the Story Mode of Super Mario Maker 2. It is set at night in the sky theme and is set in the Super Mario World style. It is posted by Stargazer, has a difficulty rating of 3/4 stars, and has a payment of 200 coins. The clear condition for this course is to reach the goal after defeating all ten Big Bloopers.
The level starts out with a small area with a Pipe giving out Cape Feathers. After getting a Cape Feather, Mario must enter the door to the very right and he will land on a Donut Block. Mario must then simply defeat all ten Big Bloopers below by stomping on them, using the low gravity to his advantage. He must then simply land in the Giant Gate, which has a layer of Spike Traps below it.
"I put a bunch of Bloopers on a planet with low gravity. There are 10 of them in total. Defeat them all, and then head to the goal. Hold while stomping on an enemy to bounce really high. Good luck."
