Sotoburu can be found in The Docks B . His colour changes from red to a pale pink, back to red and then to purple. Then it starts all over again. He'll give Madotsuki the Fat Effect when interacted with.
Trivia
- When the Cat Effect is used his color changing speed will double. He won't move towards the player though.
- When he is stabbed the colour changing speed decreases to one third of the original speed till he dies.
