Anyone have an opnion on what the fastest way to earn experience points and money in Super Paper Mario is?

kill a lot of enemys until you get at least 500 coins then go to flopside's item shop and buy the star\gold medal then go to the dotwood tree get the slow flower and use the star\gold medal. hope this helps.

Well the best way to get experience points is to go to 1-1, then go to the last room, kill the pirahna plants, then go up to the point with the question box, but dont press it yet; use thoreau to pick up the three purple squiglets up ahead and throw them behind the pipes that used to have the pirahna things, then go back, hit the question box, get the star, kill everything else to the right, then u go back to the squiglets and throw them back to the right of the pipes. then make sure the squiglet is facing you then once it starts spitting rocks, hold down 2 and try to land on them repeatedly without ever landing (youll have to use the control pad) and since u get ten more experience points per each hit, u can keep going for a while, like i got to around 3500 per hit until finally failing x3

u can do that on other levels with squiglets too, but since u move slightly each time u hit the rock thing, youll end up going into a wall usually.

go to chapter 5-4 WITH NO ITEMS and go to the pipe that continually spawns floro sapiens. have bowser fire breathe the floros til they give you sap soups. Get ten, then use the return pipe. go to saffron, and have her cook each.
Then take bowser and barry to the duel of 100 with the Sap syrups and spam the fire breath. when your health gets low use a sap syrup.
at the end, you get catch cards for paper mario 2's partners. sell them at flopside NOT FLIPSIDE cause you get more money there. Hope this helps.
