Getting Credits: Credits are the form of currency in the game. To get these, there are multiple ways. There are some secret codes, explained in other threads here on Micechat. There are minigames, explained later. And there are the dailies. The dailies are the NPC's(Non-Player Characters) you visit everyday. They are as follows. To get your credits from them, you jsut double click each character. The first time you visit each, you will recieve 40 credits and a pin from each, except the ghosts, and after that only 20 per each every day.
Phineas, Ezra, and Gus-Haunted Mansion (Go through the glowing teleporter, and continue through the rooms)
Shrunken Ned-Shrunken Ned's Shop
Captain Blackheart-Pirate's Treehouse
Create A New Song-Street Music Party Game (Just open up an existing song, hit play, stop, save, and exit.)
Also, every 25 minutes or so, you can play the Street Music Party Game, which will give you 25 credits each. Another way for credits is to sell your items, but I recommend not to. Believe me, you will regret it !
Keep in mind, this is only part of the other thread.
