Noby Noby Boy

The player takes control of a worm-like quadrupedal character referred to as Boy. Using the controller, the left analog stick moves the front of Boy while the right stick controls the back. By moving both ends in opposite directions, the player can stretch the Boy's abdomen to colossal lengths. The player can maneuver the Boy around its environment, interacting with stationary objects like houses, or AI-controlled characters such as barnyard animals.

The player accumulates points by how much they stretch during gameplay. These points can be submitted online via a character called Sun to another character called Girl. Points submitted online by players to Girl will be added cumulatively, causing Girl to stretch and unlock new levels. Beginning on Earth, GIRL has stretched to the Moon, Mars, Jupiter, Saturn, Neptune, Pluto and stretched back toward the Sun, and ultimately to Earth again, each unlocking new playable environments for Boy to stretch in.

The game was first shown at a press conference held during Sony's PlayStation Premiere 2007 event in Tokyo. Takahashi showed a silver stretch hose with two pink balls at the ends, explaining that it wasn't a controller, but a visual aid to help explain the game. A 30-second demonstration clip featuring the character "Boy" was shown.

A playable prototype of the game was showcased at the GameCity 2007 International Interactive Entertainment Festival, where Takahashi delivered the festival's Vision Statement for the year. In the demo; as many as three Boys were shown interacting on a flat plane filled with barnyard animals; their elastic bodies were used to snap, whip, entangle, and drag themselves around. The Boys could swallow animals, distending the Boys' bellies, which could then be whipped to the posterior to be expelled.

The PlayStation 3 version received "generally favorable reviews" according to the review aggregation website Metacritic. As of May 2009, the same console version sold "about 100,000" units. Since the game's release, Takahashi had said that he was "not completely satisfied with the game".
