Place it right after the sneaky move lands on screen, then cut to the victim's reaction for the payoff. Pair it with FBI Open Up when the trick gets caught, or No God Please No when the plan falls apart, letting the second clip carry the consequence while this one owns the trick.
About this sound
This short clip is Wario repeating his signature wa in a raspy, rising voice, with the notes climbing as the laugh builds and then stopping suddenly. It feels gleefully mischievous, like a cartoon villain enjoying his own trick, turning a sneaky moment into a joke at the schemer's expense. The laugh comes from Mario Kart 64, where Wario uses it to taunt rivals during races.
