Over the Hedge Hints for PlayStation 2
When you're on roads on levels when Ozzie pulls the trailor, stick to either the left or right hand side of the road and you shouln't get hit. Very rarely you'll get hit.
In level 4, "Caught In The Hedge", there is a complete the level with full health objective. To easily accomplish this, switch to the CPU at the very end of the level. They will have taken no damage and have full health.
