It's randomized so other people's choices aren't going to help. when it says something like "two long tones and one short tone" you choose right, "one long tone and two short tones" is left, "two short tones and one long tone" means forward, and "one short tone and two long tones" means turn around. "three long tones" means dig. can't really help you beyond that.
It's weird because when it says three long tones then it goes silent, I presumed I'd found something, but when digging I'd found nothing. xD So idk what to tell y'all.
