The Pokémon Center is an area where you can trade with other trainers, purchase items and get daily gifts. It can be accessed via Sam and Dan's blog, the "Trading" button on the game menu and the "Inventory" button on the game menu.
There is also a warning to log out of Pokémon Tower Defense as it might corrupt data--if you open the Pokémon Center while playing PTD, the game will be unable to save.
In the Avatar Store you can buy different avatars using your SnD Coins.
Once a day, you can participate and try to win rare prizes.
Check your items and change your avatar for this profile.
