So I have an idea for identifying cicadas which might be faster than presenting them to Batayan. I’m not sure if this has been implemented into a run yet, but perhaps you can toss every cicada you get over the course of the game, and then check with the lost and found for which number of cicadas is lower, since Long Life Cicadas and Sleepicadas are split up there. Maybe this has already been put into a run that I just haven’t watched yet, but I thought it would be an interesting topic to bring up.

I never noticed that the 2 cicada types are split up in the lost and found, that's really handy. There'd be problems with that method though, at least in my current All Kisses route. Getting the Sleepicada is a reset point around the 30 minute mark in my route, because even if I'm lucky enough to get 2 cicadas to try my luck with, it's far from a guaranteed. By the time my route gets to the lost and found with Policeman the run is over 3 hours in, so I really wouldn't want to risk resetting there just for the sake of a pretty small amount of Batayan text. At the very least, with the way my route has it, talking to Batayan wastes the least amount of time possible since I have to wait for Turtle Boy anyway, so it works out really nicely. Tossing them to the lost and found could be a better idea if it fits in with whatever route your using, but if it involves entering lost and found more than once in the whole run then it'd probably cancel out the time gain from Batayan thanks to the extra Policeman text.
