'D'S Garage 21: Koubo Game - Tana o Maku Tori' is a Japanese puzzle video game for the WonderSwan handheld console. It was published by Bandai on December 22nd, 1999.

The lone crow has finally made a friend. However, his friend is a migratory bird from the south, who must leave for the south at the end of the summer. At the end of the summer, the friend says, "I'll come back when it's full of flowers," and then he leaves. This game was born from the TV Asahi's "D's Garage 21" creator discovery program, "The Bird that Sows Seeds". The player must fill the town and fields with flowers so that the main character's friend, a raven, can return home quickly. You must guide the crow's seeds so that water will be distributed to the flowers and collect the droplets of water to kill the pests and fill the field with flowers. A two player mode is available via the Communication Cable.
