Zombie Mushroom Signal 3

Okay, now I need you to go slay some Zombie Mushrooms. The sound of the dying mushrooms should be recorded and that should cause them to drop Recording Charms upon their death.

Collect 20 Recording Charms for me. You'll be able to gather them by hunting Zombie Mushrooms.

I am sorry. I must be working you too hard. I understand.

Ah, this is the sound! Just hold on a second!

'Mushking of the Mushroom Castle is in danger. Watch out for King Pepe! Request help from the courageous heroes of Maple World who are at least Level 30.'

Mushroom Castle? I've never heard of the place...

That's not the sound...
