Hey, it is CD here staying up late like always! 
The Music Jam has arrived, and I have some cheats for it! You can get the Umbrella Pin by looking at the Pin Tracker to the side! -> To get the Green Head Phones, go to the cove and click on the box with the head phones in it!
To get the All-Access Pass, go to the Merchandise Booth at the Snow Forts!
UPDATE: How to get Black Guitar and Drums!
How to get Black Guitar:
Click the “o” in “Catalog”
How to get Drums (Thanks GH) :
Click the “dot” in the “i” in “Music”
Pretty cool huh? Hope you have fun at the Music Jam!
Awesome post CD!!! Rock on penguins!!!!!!
