Lirieke: Dungbombs Rock. Other. Mouth Organ.

You are often on the edge
You need to find all of the horcruxes

But you know, you know where not to look,
You know which of the 6 has been taken care of
Dumbledore left you a lot of clues to get through,
But he did not tell you where to go

The mouth organ, was only ever, a mouth organ
