This 2.3-second musical sting plays three rising chan notes followed by a playful yingo, bright and punchy enough to make an ordinary glance feel suddenly important. It feels funny and suddenly tense, like comic alarm arriving a beat too early. It comes from the Dramatic Chipmunk meme, where a prairie dog turns sharply toward the camera as the music swells.
