Bouncy Wario

"When a mallet hits my head, my long, toned legs turn into a spring! Not great, but it lets me jump amazingly high!"

- Wario Bouncy Wario is one of Wario's transformations in the Wario Land series of games. If hit by the hammer of an Ape, Hammer-bot, or Menhanmā, Wario will be squashed, only to spring right back up again in this state, used to spring to new heights. In all three versions, Wario has a time limit before he will return to normal (hitting a spike will also work). However, in Wario Land II and 3, pressing will let Wario jump slightly higher, while in Wario Land 4, pressing  will cause Wario to jump up until he hits an obstacle, allowing him to return to normal. When the time limit runs out, Wario will bounce one final time in the direction he last moved.

Bouncy Wario has appeared in volume 28 of Super Mario-Kun. During a fight with Spoiled Rotten, when Wario is low on health, Dr. Arewo Stein gives Hoggus a hammer. Hoggus then uses the hammer to hit Wario, transforming Wario into Bouncy Wario. Bouncy Wario then proceeds to defeat Spoiled Rotten. Wario also uses this form to defeat Golden Diva.

Trivia

 * In Super Mario Galaxy and its sequel, Mario can use a similar form: Spring Mario.
 * The way Wario looks in Bouncy form is similar to the way he looks after eating a Springo Candy in Mario Party 8.
