Ty the Tasmanian Tiger 2: Bush Rescue Codes and Unlockables (PS2)

TY the Tasmanian Tiger 2 picks up where the original popular action platform game left off. The cast of characters from down under has grown and so has the action! The evil Boss Cass is up to his old tricks. After breaking out of Currawong Jail, this feathered villain has re-instated himself as the dictatorial ruler of Cassopolis, a high tech island home to lizards and birds. Now Cass has hatched a plan to take over the world with an army of Uber Reptiles. It's up to our boomerang-wielding hero, TY and his newly formed team of Burramudgee Bush Rescue mates to stop Cass!

Fourbie Trick
In case some of you don't know what the Fourbie is, it's the red truck that you use to go places. There is a trick to get opals while riding the Fourbie. It only works once per game. Not a game as in the entire disc, but a game as in a single file. The trick is to hold down the R2 button while driving on the road in the Fourbie and hold the left analogue stick to the left or right. It doesn't matter which way you hold it though, as long as it makes the Fourbie turn in circles. After a few seconds of spinning, you'll get some opals. You can use opals to buy stuff. Enjoy this nifty little trick!

Regaining life fast
When you get hit, you can go swim underwater, come back up and have full health.
