When you get inside the room, click on the girl to play a mini-game. The objective of the game is to collect all 10 magiswords.
When you win, you get two prizes, an Oinkus Magisword, which grows big and makes a pig snort, and a Tomato Magisword, which throws a tomato at another Poptropican.
If you are having trouble with the mini-game, below is a video tutorial of it!
Until next post everybody.
