The Collector's
System

Step 1:

Hover over "My Room" with your mouse on the left-side of the main menu and click the "Collector" button.

Step 2:

The first thing you'll notice will probably be the fancy stickers below the menu options. Just like the menu states, they're the materials needed in order for Panda (an avid sticker collector) to trade her goodies with you.

The stickers you obtain through races are random (showing at the end of each scoreboard). However, if you're after a specific one, they appear more often depending on the mode you're playing in. For example, Jack's Beanstalk sticker will show up more often in the "Jack and the Beanstalk" mini-game.

Step 3:

Clicking on the costume tab will give you a list of all the clothing items you can trade your stickers in for. All clothing items will come with their own set of ability cards and all accessories will come with their own utilities.

Note: You can not use a recycler (a tool that allows you to take back ability cards already binded to clothing) on items obtained through the Collector's System.

Step 4:

Once you've decided on the clothing item you'd like to trade with Panda, clicking on it will give a list of the amount and type of stickers needed in order to complete the exchange.

When ready, click the "Trading" button and the exchange will begin!

Through the Collector's System, not only will you be able to trade for costumes, but you will also be able to exchange for housing decorations and cash shop etcetera items!

All Collector items traded with Panda will appear in your inventory.
