How to Get by the Monster in Epic Mickey

Jump across the platforms over the river once you enter the belly of Shadow Blot.

Defeat the three enemies that you encounter and carry on in the same direction until you can see Mickey's heart being guarded by giant tentacles, called bloticles. Drop down to the lower level and take out the enemies here. Pop the green boil on the tentacle.

Climb up the platform to the right of Oswald, who is currently trapped. Go through the tunnel and pop the other boils that you pass.

Avoid the blot-toons in the room after the tunnel, as they are indestructible. Explode the boils here and the bloticle will fall away from Mickey's heart.

Return to the heart chamber through the tunnel and defeat the enemies waiting for you. A door will open once they are all disposed of.

Destroy the boils on the bloticle while dodging the blot-toons. A second bloticle fall away from the heart as a result.

Go back to the heart chamber and defeat the enemies to open the door to the final tunnel. Climb the ledges to reach the tunnel and head into it.

Pop the boils as you jump from platform to platform in the tunnel.

Get on top of the bloticle when you reach the chamber. This is an easy way to avoid the blot-toons.

Walk along it popping every boil you see. Return to the heart chamber once the third bloticle has fallen.

Burst the boils on the bloticle in this room, but the tentacle will not die like the others. This is because there is one more boil at a high point of the room.

Climb up to the entrance of the highest tunnel. Pop the boil up here to destroy Shadow Blot. Mickey's heart is also freed so he can put it back in his chest and return to his own world.
