w00t!In the Bandai America showroom, there was a large Tamagotchi on display, at least a foot in height. This DEKA TAMAGOTCHI ("DEKA" meaning "huge") can connect with regular Tamagotchi using its IR port, and share special items or play special games. In Japan, the DEKA TAMAGOTCHI showed up at special retailers and fast food restaurants, allowing visitors to add a unique character exclusive to the DEKA TAMAGOTCHI to their Tamagotchi Friends List.
Unfortunately, the complicated licensing issues make it difficult to bring the DEKA TAMAGOTCHI to American fast food restaurants... but Bandai hopes to bring DEKA TAMAGOTCHI to special retail locations so that people can bring their TCv2 to connect and communicate.
Fortunately for people who already have Tamagotchi Connection, TCv2 is backwards compatible, with an added menu that lets you choose whether to connect to an original or V2. And fortunately for me, DEKA TAMAGOTCHI is also compatible with Version 1, letting my Hinotamachi "Pha" visit the special Tamagotchi character "KORE-A-N". I watched as Pha played on the teeter-totter with KORE-A-N. The two of them then "travelled" to my hand-held Tamagotchi Connection, where KORE-A-N gave Pha a little present... a teeny tiny Tamagotchi of her own!
