Blow Up Trash Guide

You'll need to find a hidden star in the third Dreadnought's star mission.


First, run to the underneath of the saucer, there will be a warp pipe which will take you to the garbage dump.

There will be a droid that needs your help, the planet has been covered in trash and you need to get rid of it in 30 seconds.

This can be difficult to do as the Bob-ombs take a while to explode.

Here's how to do it!


Throw the Bob-ombs at the gold things on the floor.

Toss one at each of the six gold symbols, begin with the bottom left then go along the bottom row to the right.

Then throw two Bob-ombs, into the top left, then the top right.

If you do this correctly, all the trash will be destroyed in the 30 second time limit.



  • Bob-ombs explode 10 seconds after thrown
  • You can pick up and move a Bob-ombs after thrown
  • Make sure to do the two Bob-ombs in the corner last
