Overview

Bowser Jr. ejects himself from the Junior Clown Car. The Junior Clown Car slowly falls to the ground, dealing 5% upon contact and then explodes while dealing 13% with high power when the move is used in midair, whereas it will simply explode after a brief period when used on the ground. When Bowser Jr. is out of the Junior Clown Car, he is not rendered helpless and can still attack with a hammer that deals 10/15% (or in the case of the Koopalings, their respective wands), which is powerful enough to KO at medium to high percentages. He is also able to airdodge once. However, taking any weak hit while out of the Junior Clown Car prevents another use of the move without button mashing or landing. The Junior Clown Car's angle usually sends opponents at a favorable position to follow up with the hammer swing.

This move received a few updates, but was overall buffed with the exception of one. Update 1.1.0 haves Bowser Jr. receive more air dodge frames while rising, although a nerf exists where he can no longer air dodge more than once in midair, which reduces its safety and recovery. Version 3.1.0 hitboxes are more reliable to connect. And version 9.0.0 has less startup, which helps him quickly rise in the air.
