From the Super Mario Wiki, the Mario encyclopedia
Blooper Pools is one of the fourth routes players can travel in the River Survival mode of Super Mario Party.
The route starts with several Bloopers amidst several obstructing rocks and a short waterfall. A long slight left waterfall follows amidst several more rocks and Bloopers, where the first Minigame Balloon appears at the base of the waterfall on the left. After the 3,500-meter mark, two pairs of Dash Panels follow, as well as additional rocks and the second Minigame Balloon not long after. After a winding path with another small waterfall, the players approach the third Minigame Balloon moving away from them, as well as the fork leading to either Kamek's Curse or Cheep Cheep Swarms.
