Wario using Hyper Suction to collect coins
Use Hyper Suction by pressing the L Button to suck up lots of coins at one time! Use this trick to grab coins really fast!”
Spriteling, Wario World

Hyper Suction is a Special Move in Wario World. When the player presses L Button or Z Button while there are loose coins around, Wario opens his mouth wide in a Kirby-esque fashion and collects them by sucking them up. Wario cannot attack and moves very slowly while Hyper Suction is being used. In Super Smash Bros. for Nintendo 3DS / Wii U, Wario has a custom special move that is somewhat similar to Hyper Suction, though it is used as an attack and called Inhaling Chomp.
