Anything with a balance meter can be used to get alot of points. Just move the pointer slightly. Do not move it hard, or you will wipe out. Also with lip tricks or grinds, keep pressing Triangle to switch tricks. For example, if playing as young Tarzan and you do the lip trick "Takes A Steady Hand", press Triangle to switch to " Close To The Edge". This is very useful for getting high and extreme scores.

Okay to get Romeo is simple just go up to that mean and crappy tough kid and beat the high score. But if that don't work than do something else for a guy, like Cap'n Salty.
