After being shot out of cannon from the Bouncy Houses of BoomBoom Avenue, clowns land into huge ball pits. The ball pits are filled with magical, scifidelic balls when they splash, completing their journey into the loading docks outside the BONK Factory. This is the epic climax of the Clown Down Experience.
Once the clown successfully emerges from the pool of balls, another giant claw comes down fishing out the clown so it can be loaded into the BONK Factory for immediate harvesting.
As part of the entire experience of abduction, the ball pits are considered a great time by the Clowns who actively seek out the opportunity. This is part of the Clown Down Experience and why clowns frequently migrate into the BoomBoom Avenue in the first place, never to return.
