Place this clip at the exact frame of the win, then follow it with kids cheering to sell the mock ceremony. If the moment is an unlock, lead in with the zelda item get first and let this line close the sequence as the payoff.
About this sound
This is Luigi shouting his victory line Ya-haa I'm the best in a bright, high pitched game voice, lasting just over three seconds. It feels smug, triumphant and gleefully over the top, like a tiny win turned into a championship celebration. The clip comes from Mario Party 2, where Luigi says it after coming out on top.
