How do I beat shadow blot at Mickeyjunk Mtn?

wait till he smashes into the ground
at this point he'll start trying to suck you in just throw paint or thinner in his mouth as if you were fighting a Slobber

Use a Watch sketch before he starts inhaling so you have more time to spray. Alternately, shoot a Guardian at him to make a big hit really fast.

To defeat the shadow blot, first he'll throw thinner at you first three balls of thinner, as you keep hitting him, he'll start to throw four, then five. If you get past the thinner, but watch out, if you get too close to him he'll try to hit you. After the thinner, he'll try to dash through you, then he'll dive on to you, then watch the shadow on the ground and keep moving or else you'll get hit by the thinner meteors he throws down, when he lands, go over to him and then he'll start to inhale you, then use thinner or paint and aim it into his mouth. If you see him holding his neck, then that means you did it right. Then he'll throw more thinner balls and then he'll dash through you, and then he'll throw a blue ball but it won't hit you if your still, when it hits the ground, you'll see a blotling come out, you should kill the blotling first before you move on or else he'll hit you and it will be very hard doing it that way. Then he'll dive again and do the same thing. Then he'll throw more thinner balls and then a big thinner ball, just keep moving and you won't get hit. Then he'll summon more blotlings and dash through, then he'll dive again and do the same thing. Then the pattern of his attacks will change. Like this:thinner balls,dash,more thinner,more blotlings, then dive. To finish him, you'll have to hit him 3-6 times depending on how accurate you defeat him with the thinner or paint. If you get hit, Then get health from the boxes, but be careful, don't use them all at once, use them wisely. When he throws thinner, use the walls as shields, if the thinner hits them, use paint to restore them.
