This clip comes from material connected to Undynes Life, where it marks an entity being teleported into the Elemental Monsters Merge dimension. Its original file name links the effect to a Minecraft portal, which explains why the teleport feels so familiar to players even outside that specific project. Online, short portal and teleport sounds circulate widely among game editors because they can signal a world change in under three seconds without needing dialogue or a title card. That instant readability is why this kind of effect keeps appearing in edits, memes and gameplay clips.
