The name of the demon is Amdusias. Unlike most demons, Amdusias has admirable musical talent and can play just about any instrument. But, of course, he uses it to do harm to others, so you must keep that in mind. The Dark Portal in the [map 104040002] is the hiding place of Amdusias.

But everyone has failed to enter. It was later discovered that a person needs a very loud instrument to enter that portal.

I need a few items in order to make an instrument like that.

I'll make you an awesome instrument that will give you access to the portal if you bring me the following items.

15 Orange Mushroom Caps
2 Octopus Leg Stick
1 Pumpkin Head

But you really don't have a choice…this is the only way.

Job well done.
I'll make you an awesome drum with these items.

You don't trust me? I used to be a renowned musician in the old days!

Give me a few seconds.

It's finished.
What do you think? Isn't it awesome? Haha!

You'll be able to enter the Dark Portal where Amdusias is hiding using the Darkween's Monster Drum. But you don't have everything you need yet.

Talk to me again.

Bring me 15 Orange Mushroom Caps, 2 Octopus Leg Sticks, and 1 Pumpkin Head.
