Instructions
Play the arcade game entitled "Booger Gets an A." When you complete the game, Booger receives check marks on his report card. Achieve 3 checkmarks and you'll receive a trophy.
Pass all 20 levels of "Bounce 'N Burst" and you'll receive a trophy for that arcade game. You can also finish "Candy Bash" to receive a trophy, or complete "Operation Gumball."
Go through a variety of other arcade games for the opportunity to win trophies. Games like "Zingoz Bounce," "Polar Plunge" or "Goober's Lab" give trophies randomly to those who pass the games. Typically, the odds of collecting a trophy on these games are one in three.
