Place it at the exact cut where the creature appears in your timeline, after a pop sfx to flag the entrance and before the enemy spotted callout if the scene turns into a chase or battle sequence for viewers.

This is a sub-second creature cry, a short raspy electronic call with a rising bite that ends quickly. It feels playful but slightly startling, like a small monster announcing itself in the middle of a quiet moment. The brevity keeps it punchy rather than cute, so a single press reads as an exclamation rather than background noise during a scene.
