INFO ON SONIC RUSH ADVENTURE!!!

Ds and Sonic players and readers alike!!
I have major info on Sonic Rush Adventure! (SRA)'s storyline, starts out with Tails (Miles "Tails" Prower) and Sonic, looking for something, when a huge gale makes them blow way off course! When they land, they land unscathed, but really lost. Then, a little feisty little character shows up, who notices they need to go to sea, then starts gibbering about how all her plans for the sea went wrong. Tails offers to help her back on her journey, if she will just find him some stuff to make some machines to travel across the water. Well, even if he asked her to do it, you still have to be Sonic to go and find them on the 3-d level. When Tails has finished, you have a machine that you are to use to go find some not so isolated help. Well, there is one thing about SRA that is told everywhere, pirates! Searching for treasure, and not gonna let Sonic stand in their way. Now, there are 16 islands for you to explore (and find), but after you are done with each level, and amazing 3-d boss battle, which takes place on two screens, happens every time.
Now, when you get some parts for going across the water in the 3-d levels, you end up making a sailboat, a submarine, and something or rather. Now, the sailboat sounds sorta wimpy huh? Well, it is loaded to the brim with weapons, ready to flood any vessels in your way!!!! Oh, right, the other machine is a hovercraft!
Now, before I go, I need to tell you that Blaze from the alternate dimension comes in again. And it is your job to find out why on your journey.
Good Luck.
WAIT!!! I forgot to say the worst thing about SRA. You have to use the stylus and the touch screen for a few things!! Me, being a hard-core gamer, really don't like the touch screen very much, and I would hate it if, these moves have to be done on the touch screen!
Good Luck.
