(Japanese: おさわり探偵 小沢里奈 ライジング3 ~なめこはバナナの夢を見るか?~, Hepburn: Osawari Tantei Ozawa Rina Raijingu 3 ~Nameko wa Banana no Yume o Miru ka?~), released officially in western regions as Touch Detective 3,[3] is a point-and-click mystery adventure game for the Nintendo 3DS which makes use of the device's touch screen.

The game features Mackenzie returning to the main character role as she faces a new detective rival,[1] and once again takes her arch-rival, the Cornstalker.

[6] The gameplay remains true to the previous games, with the player controlling main character Detective Mackenzie by way of the touch screen.

Penelope turns up during their meeting and claims that her bananas have been stolen, and Norman declares that the one to solve the case first will win their challenge.

After proving herself by finding the keys that allows access to the village, Mackenzie is informed that the gnomes have been taking garbage to use as a barricade whenever Mecha Funghi attacks.

Mackenzie, Penelope, and Chloe, help build barricade for the gnomes, only to discover that Mecha Funghi is very small and non-threatening by human perspective.

Post-episode content reveals that Mecha Funghi was actually an alarm clock that Norman illegally dumped, which awakens someone by flashing a laser-esque flashlight.

Suspecting something suspicious, Mackenzie discovers that the Cornstalker is attempting to get the competition prize, an OOPArt crystal, to create a perpetual motion machine.

A new determined Cromwell modifies the car again (this time not following the official regulations); Mackenzie sets a record of thousands of meters, and is awarded the crystal.

As they investigate the townspeople, they find one other person, the sweet shop Granny, who is also unaffected, although the pair are unable to understand what links the three of them together.

Mackenzie and Daria eventually deduce that the only people who are not affected by the trance are those who haven't written a wish paper for the Star Festival, and conclude that the Cornstalker's plan is to steal the hopes and dreams of the townsfolk via their tanzaku.

Mackenzie and Daria track the Cornstalker and the evil scientist to the top of the town's giant bamboo tree, where they are trying to use the crystal's energy in a plan to steal the hopes and dreams of everyone in the world.

Its explosion sends Mackenzie falling from the tree, but she is saved by Norman, who hadn't gotten his hope stolen either, since he never wrote a tanzaku, not being a resident of the town.
