Use it at the plant-selection beat, then follow with a Pop Sound Effect as the plant lands on the lawn, and finish with a Click Nice Sound Effect when the defense is set. That order keeps the choice, placement and confirmation clear in an edit.
About this sound
This 0.6-second pickup chime plays when a seed packet is grabbed in Plants vs. Zombies, a bright, clean little blip that feels instantly familiar and playful. It gives a quick lift of nostalgia and satisfaction, like choosing the right defender just in time. It comes from PopCap's 2009 tower-defense game, where its menu sounds became part of the game's identity.
