Lets talk about Tamagotchi Connection: Corner Shop 2 NDS

In "Tamagotchi Connection: Corner Shop 2", shop owners must keep their
bizarrely adorable Tamagotchi partners happy by earning “Gotchi points” through
performing mini-game tasks for the customers. Gotchi points can be used to
clothe, feed, and care for your Tamagotchi partners. As more points are
collected, new types of shops for players to open will become unlocked. Shops
not seen in the original such as the Bowling Alley and Sushi Bar will be
available, as well as upgrades to old favorites like the Concert Hall where
players can sing along to the music with the DS’ microphone. In "Tamagotchi
Connection: Corner Shop 2", catering to the needs of your customers will be
essential in keeping the Tamagotchi happy. The five different happiness levels
will determine the dialogue that occurs between the player and their Tamagotchi
partner, and nobody likes a grumpy Tamagotchi!
