PS2 Wallace & Gromit In Project Zoo Cheats

Aiming At Distant Targets:
Gromit automatically sights enemies in third person view. When you hold the L1 + L2, the auto- aim is turned off, allowing you to aim for distant or difficult targets.

Destroy Spike Balls:
To destroy a spike ball, perform a smash jump on it a couple of time, and they will explode. For the giant spike balls, you will need to to this a few times. Just make sure that you don't do it while their spikes are sticking out.

Finding Coins and Tools:
Coins and Tools will make magical chime sounds when you are close. Look around using L1 and L2 if you do not see them the first time.
