Disney Imagineering has just shared via Instagram a preview of the new theme for the slide at Luna Park Pool at Disney’s BoardWalk Resort.
The pool that was previously clown themed will be rechristened “Keister Coaster” at feature Mickey and friends.
Imagineering had this to say:

Oh boy! Here’s a sneak peek of our Disney Imagineers installing the new graphic design on the Keister Coaster slide at Disney’s BoardWalk Resort at @WaltDisneyWorld. When the slide reopens soon, guests will have the chance to see Mickey Mouse and his pals clowning around as they splash down into Luna Park Pool.
The updated slide is expected to open before the New Year.
Gray is a lifelong Disney fan! From Disney+ to the parks, he loves it all. His favorite Disney movie is Beauty and the Beast, and his favorite attraction is The Haunted Mansion.
But the sign in the picture is spelled wrong??
Yes, that’s correct. I believe they’re working on getting it corrected.
