Place it at the reveal in a surreal edit, after a quiet setup clip and before a reaction sound, so the moment builds toward the character's entrance. Follow it with Sad Meow Song when the joke turns soft, or Cat Laughing Meme Sound Effect when the reveal is meant to stay playful.
About this sound
This 10-second music clip carries the clear sung line 'we live, we love, we lie' over a sweeping electronic arrangement, with a bright melodic build and a processed vocal. It feels oddly uplifting and dreamlike, turning a plain reveal into something surreal, nostalgic and unexpectedly heroic. The line comes from Alan Walker's The Spectre, released in 2017, and later became tied to the Smurf Cat meme.
