Touch! Kirby

For the Line Trial, you will be very lucky if you have to use any ink, especially if you are playing as Kirby. You can copy the wheel and spin to the end. If you are playing as a different character, you must tap all of the blocks at the correct time. If you make a mistake, you must dash back to the beginning then back to that spot if you do not want to use any ink.

For the Line Trial for Ravine Road in Rainbow Run, you do not have to use any ink to get to the end. Just keep tapping Kirby (or whatever character you are using) and you will make it to the end. The air will push you up and you will never fall in the pit. You may needt to use a maximum of 10 ml, but you will get three medals this way.

When you pick up a powerup that lets Kirby hover, such as Beam or Spark, hold Kirby in midair by pressing him with the stylus. He will hover until the stylus is removed, and the paint supply recharges while he hovers. This is useful for when Kirby is too high in the air to recharge normally.

There are more versions of Kirby when you beat the game. Here they are and how you can get them.

Waddle Dee Ball-Finish the game once. When you start a game from the save file, Waddle Dee will be revealed as a new playable character. He only has 4 hit points and can't obtain powers. Also,he's lighter than Kirby.
