Portrait of a Popular Monster: Octopus

I'm really worried. You see, I wanted to thank everyone who helped in celebrating MapleStory's 5th Anniversary, but I'm short-handed right now. Do you think you can help?

Okay, [Name]. All you have to do is to bring me a Portrait of an Octopus . In order to draw the portrait, you have to collect an Mystical Watercolor Paint and use it on a blank piece of drawing paper.

Fine, suit yourself. You're going to regret not helping the beautiful Cassandra.

You don't seem to have a sheet of Magical Drawing Paper. Forfeit the quest and talk to me again, so I can give you a new sheet of Magical Drawing Paper.

Hmm... I don't think you've completed the portrait. Please bring me a completed portrait.
