Place it at the start of a flashback sequence, just before the older footage begins, then follow the reveal with JoJo To Be Continued for a dramatic pause or Mayuri Tuturu for a lighter anime reaction.

This is a just-over-one-second playful vocal clip centred on a repeated Pikachu-style 'pikachururu' sound, presented as a quick flashback cue. It feels silly, bright and instantly meme-ready, like a tiny cartoon interruption that lands before anyone can react. It comes from a TikTok audio cut credited to @zedejoze.
