The Melancholic Viking is an NPC that spawns in The Park island, located on a smaller island in the spruce tree section. He has a shop that is locked behind a small task that you need to complete to unlock his shop.

His shop once he has been turned into the Joyful Viking consists of:

• The Viking's Tear
• Travel Scroll To The Jungle Island
• Raider Axe
• Experience IV Book

To unlock his shop, you will need:

• Fish Hat
• Magical Water Bucket
• Two Raw Fish
• 200 Intelligence

How to unlock it?

• Place a Raw Fish in the Furnaces found in his home.
• Start to splash by crouching with the fish hat ability.
• Put water in the fireplace using the magical water bucket.
• Keep splashing with Raw Fish in hand until his shop opens once the Viking has been struck by lightning.

Extra:
There is a fairy soul on the roof of the Hut where the Viking lives.
