About this sound

Rex's excited My source of power line from Toy Story captures the anxious dinosaur's sudden burst of confidence, perfect for power-ups, victories, and reveals.

The clip is a short, high-energy voice line from Rex, the nervous green Tyrannosaurus from Toy Story, as he declares that he has found his source of power. His voice rises with childlike excitement and relief, shifting quickly from worry to triumphant certainty, with a slightly squeaky, earnest delivery that makes the moment feel both heroic and funny. Because Rex is usually the most anxious toy in the room, hearing him sound suddenly confident lands as a joke in itself, turning an ordinary boost, discovery, or comeback into a playful, cartoonish celebration.

Pro tip

Drop the line right as your character grabs an item or unlocks an ability, then cut to their reaction. Keep it loud and avoid placing it over dialogue, since Rex's punch comes from the sudden shift from panic to pride.
