"Three Blocks" is the conjectural name of an unnamed adult character programmed onto the Tamagotchi Connection, as well as the Version 2 and 3. It can only be obtained through debugging the unit. The character cannot be accessed by normal means and it is unknown what purpose it was originally for. It has been suggested that this character was intended to be a Deka Tamagotchi; when it connects to a Tamagotchi Plus, the Plus will react as though it were connecting to a Deka Tamagotchi unit. However, this character was not programmed into any of the Deka units.
