Place it on the exact cut between locations, then let the new scene settle before adding the next cue. Follow a successful arrival with Victory Fanfare, or let a failed escape land with Sad Trombone to mark the miss.
About this sound
This is the brief descending swoop heard when Mario slips into a pipe in the Super Mario games, a hollow, cartoonish slide that lasts just over a second. It feels playful and instantly familiar, like a secret doorway opening in a familiar game. The effect comes from the Super Mario series, where it marks the move into a tunnel or hidden area.
