Can any one help me with these skill points... transported: aridia ..

I'll try!

transported: aridia - destroy three of the vehicles in the air (recommened devastator for this!)
tricky: rilgar - Do a Twisty McMarx in a race (all poses and a flip for each)
speedy: rilgar - I'm in the same boat with you there!
jumper: batalia - read above
eat lead: batalia - I think you have to destroy a tank with a Sand Mouse, don't know where the house is though.
alien invasion: pokitaru - still need to get that one
sitting ducks: oltanis orbit - destroy all those ships on the rooves. They're cargo ships or something.
blast 'em: oltanis: er...
heavy traffic: kalebo III - go through that long grindrail without losing a drop of health, use Pyrocitor to get past mines.
magician: kalebo III - the only thing I know here is you have to score a certain amount of points that's above 1,000.
careful cruise: veldin orbit - do the water thing without losing a drop of health.

I'll try.

For transported- you have to destroy 3 of those flying ships.
trickey - you spin 4 times (while in the air) and press L1, L2, R1, R2 one for each spin....

speedy - you have to finish the race in 1:35 or less minutes
jumper-get though the grind rail without geting hurt
eat lead- I'm not sure but I think you have to destroy all of the tanks with a sand mouse.

There is a sand mouse behind the bilding on the right.
Alien Invasion: Shoot down three Blarg saucers with visibombs.

(They don't fly in patterns so just pick one out and start flying. Don't fly too high or the bomb blows up.)

Sitting Ducks: Destroy all cargo ships in the base.(Use the visibomb and search and kill.

You might have to go to different areas to get some of them.)
Blast 'Em!: Destroy three Marauding Blarg ships.

Heavy Traffic: Traverse the long Grindrail without hitting any mines or cars.

Magician: Attain a tricks score of 4500 or better on hoverboard race.
Careful Cruise: Complete water traversal without losing any hitpoints.

(This is a very hard Skill Point. Just try and Stay low and stay away from the lasers and mines.)

Good luck
