Switch Galaxy Ultra

In a lot of levels, you're racing past other ships (the ones that you can also steal money from for the Robin Hood trophy). These ships can be destroyed when you fly through the bomb icons that also make the glass panels blow up.

Just play through all the levels, flying over the bomb icons when they show up, and you should get this before finishing the game. It unlocked for me during the Vestia II level (where you get the penultimate comic episode).
