After they realize that the noise-maker is invisible, Reiner suggests that it might be a ghost, which neither of them are equipped to see. They debate for a bit (while inhaling berry-scent) before deciding to check out the squirrels first. Animal curiosity!

Alas for them, they fall asleep. But hooray for them, they get presents! Win win?

After they awaken, they'll check to see if there's any remaining sign of whatever made the noise.
