I think Alicia Stella claimed that the tunnel following the dip drop (where the spinning beehives were) would have projections of Louis on the walls. But that's only the first part of the Laughing Place and never had many physical characters to begin with. At DL and Tokyo, this tunnel doesn't even have any figures at all, whereas WDW had figures of the main Brer Trio (with Brer Bear being attacked by bees). Those particular figures are located further into the Laughing Place after the final small drop at DL/Tokyo.
I didn't listen to the entire podcast, but Alicia apparently also said there would be a segment of Mama Odie shrinking guests down to tiny critter size, with the dip drop being used as the "effect" for that transformation, and the final lift and drop being what gets us back to normal size. While I must stress that I haven't heard anything actually contradicting this claim (I have no specific information on the Laughing Place at all to say if anything is true or not), the shrinking plotpoint just sounds so random, pointless and out of place to me. So I dunno.
