Place it at the very end of a part, after your last action beat and before the credits card. Follow a failed attempt first with SpongeBob Boowomp Sound Button, then close with this clip, or alternate episodes using JoJo To Be Continued Sound Button for variety.
About this sound
This clip is the short narrator announcement that says next time on Dragon Ball Z, delivered as a bold episode preview tease in about three seconds. It gives a listener a dramatic, suspenseful lift, like a story is pausing at its biggest moment and promising a bigger payoff when the action returns in the following episode.
