Place it as the final beat of an outro, after your closing words and just before the end screen appears. Follow it with Kids Cheering to turn the thank-you into a small celebration, or put Zelda Item Get before it when a subscriber goal is reached.
About this sound
This is a short Spanish voice clip, lasting about three seconds, in which an altered voice says 'Gracias por suscribirse,' or thank you for subscribing. The delivery is warm, upbeat and a little playful, with the voice effect giving the familiar sign-off a light, cartoonish lift. It feels like a cheerful closing note, made to leave a viewer smiling after a video ends.
