Instructions
Get to the top of Mickeyjunk Mountain. Jump in the center of each rocky platform for stability. Watch the Shadows Blot's arms during battle; when he throws a bolt, his arm will curve, indicating where it will land.
Run in circles to avoid paint thinner rain. Shadow Blot will place his palms upward to hint coming rain. Kill any paint splatters before attempting to fight Shadow Blot directly.
Aim your paintbrush toward Shadow Blot's open mouth when he yells and spray thinner to damage his health. Avoid standing directly in front of his mouth, as he will suck you in. Continue attacking in this manner until Shadow Blot is defeated.
