Place it at the exact moment the morning scene begins, then follow it with a round of clapping once the character is finally up and moving. If they hit snooze again, let a fail sound answer the second alarm instead of repeating the opening.
About this sound
This 0.4-second clip pairs a rising slide whistle with a bright alarm-clock bell, the whistle zipping upward before the bell rings out. It feels brisk, cheeky and cartoonish, like a joke alarm going off at exactly the wrong moment. It comes from the 1943 Goofy cartoon Victory Vehicles.
