Rango

Most likely, you will not have this achievement by the time you complete the game. The achievement is not cumulative, so you do not need to have 150,000 at one time, just a total of 150,000 stars all together, so feel free to spend stars whenever you like. The best and fastest way to grind this out is to use the following method:

Note: Before using this method, it's best to upgrade both the power and range of the Charged Attack to 3 stars. Also fully upgrade any abilities that give you star and/or multiplier bonuses.

- Use "Tale Select" and choose to replay Level 1.

- Progress to the end of the level where you have to fight the worm that curls up in a ball and rolls around pooping out smaller worms. He normally spits out six at a time.

- Do not attack the big, rolling worm.

- Charge up your X button attack and take out the smaller worms. If you can get them to group together and take out several of them at once, you'll get even better bonuses.

- Keep killing the small worms for as long as they keep spawning, then finish the level.

- Rinse and repeat. You can usually rack up about 30,000 stars in one go (about 10 minutes) doing this.
