Place it at the start of a museum-visit edit, after a WhatsApp Message Sound to set up an incoming voice note, and follow it with a Kiko Laugh straight after the warning.
Über diesen Sound
This is a short spoken clip, just under five seconds long, with a voice warning children in Catalan and Spanish to be careful because the museum is wetting itself. The clash between a serious warning for kids and such an absurd, childish image makes it feel silly and light-hearted, like a joke shared between friends rather than a real alert.
