-Early morning along the riverfront finds a paperboy on his route...What was that???
-Later on, Ken buys a bagel sandwich for Natsumi & after visiting with the kindergarten kids heads back to Bokuto Station but then...What the? A monkey? Not only does he make Ken lose control of his bike but he also makes off with Natsumi's sandwich! Apparently this stray monkey has been creating a nuisance in the area for the past month or so. What do you think, Toukairin? And what's in the envelope?
-Easy, Miyuki-Ken's OK! Can't say the same for your sandwich, Natsumi-This must be some sandwich indeed for you to get so worked up about it! BTW, what's so interesting in the mag you're reading, Yoriko?
-According to the Chief, there have been several reports of a strange animal appearing along the river so they are to assist Community Affairs in stepped-up patrols. OK ok, Natsumi-It's the monkey & yes, watch out for it & patrol the waterfront.
-One more try for the bagel sandwich (Plus some cheesecake) for Natsumi before going on patrol...Hey, that monkey snatched my food again! Come back here!
Meanwhile, Toukairin's helping an elderly couple find their cat Tama who's been frightened by that same monkey-Good job! A lot better than Natsumi vs the monkey, that's for sure!
-Leave it to Yoriko to turn the search for this mysterious animal into a possible moneymaking scheme.

And judging by the number of strays Toukairin brought in, the idea of putting yourself in the animal's place does seem to work better than blindly chasing it, eh Natsumi? Also, we find out what was in that envelope-Toukairin's been re-assigned to the Mountain Police & will be leaving sometime next month.
-Some late night training for Toukairin (As always) but when he climbs back up to the station roof he finds a visitor in his tent...The stray monkey! And before long, they become buddies! Sorta reminds you of Natsumi, eh Toukairin?
-Yoriko & Aoi try searching the river again with no results...Wait, there's the UMA! Catch it, Saori! Oh, it's only a stuffed toy...Too bad, Yoriko! Plus, you're about to get a lot of help!
-So you think you'll catch the monkey this time, Natsumi? At least you got the right idea by thinking like her but she grabbed your food again! No worries though-Miyuki tagged the monkey with a tracker so they can follow & catch up with her this time (With help from Ken & Toukairin) at the Kinshi Bridge.
-Man, Natsumi's really determined to catch the monkey, isn't she? First on her Motocompo, then she chases it up onto the railway just as a train is approaching!
Like I said before in season 1, Toukairin's some guy, isn't he?
-Well, one of these animals might be an UMA...Who knows, you might get at least 100,000 yen for them, right? And Natsumi finally gets her sandwich thanks to Toukairin...And yes, he named the monkey after you so be nice & share it with her, OK?
