Mini Bowser Jr.
From the Super Mario Wiki
(Redirected from Mini Bowser Jr)
A Mini Bowser Jr. is a wind-up toy modeled after Bowser Jr. and makes his first appearance in Mini Mario & Friends: amiibo Challenge. He's only unlocked via Bowser Jr. amiibo. His unique ability is crossing spiked floors without getting hurt and losing a life, thanks to the mini Junior Clown Car he is always riding. Every time he steps on spiked floors a helicopter sound can be heard and dust is blown from the Clown Car's propeller. He is voiced by Caety Sagoian and sounds similar to Bowser Jr., but higher-pitched.
