Vulkin with a Hot Dog

Vulkin is an enemy that the protagonist can encounter in Hotland.



As its name implies, Vulkin resembles a volcano, with the conical structure that is a common characteristic of volcanoes. Lava can be seen leaking from its crown, and little puffs of smoke can be seen spewing out steadily. Vulkin usually has its eyes closed and a permanent blush. Due to its cheerful attitude, it is usually seen smiling.


Vulkin is a kind creature who, unfortunately for the protagonist, thinks its lava can heal people.

In Battle

Appears With


  • Its "Thunder" attack is a cloud at the top center of the board, firing bolts at a wide angle toward the SOUL, the bolts separating more the farther they travel. A variation of this has the cloud move.
    • Getting hit by this attack causes the SOUL’s SPEED to increase.
  • Its "fire" attack is two columns at the right and left edges of the board, shooting fireballs toward the center; the fireballs go back to the column from which they were fired.


  • This monster can be spared by hugging or encouraging it. However, encouraging it increases its AT, and hugging it decreases the protagonist's DF.
  • Criticizing them discourages it from attacking altogether, which is useful when there is another monster.
