In Black Widow's dream, click the turpentine and it will fill the sprayer. Equip the sprayer and jump onto the three paintings to clean the writing off.

In the first visit, you can only dig down 2 levels until you hit a metal barrier. Avoid or hit the ants and you will find the empty sprayer you need for Black Widow's dream. Once you have the Stopwatch from Captain Crawfish's dream, you can nearly complete the Binary Bard's dream, where you will find a Diamond Drill that can cut through the metal squares. When you return to Dr. Hare's dream, you will find him in the bottom of the anthill, along with his Carrot Totem.
The empty sprayer (from Dr. Hare's dream) is filled with the turpentine from Captain Crawfish's dream. Get the red key above the ship's door and opene the chest on the lower deck.

At the row of steel cubes at the bottom of the second level, you will find the sprayer. In Black Widow's dream, click the turpentine to fill the sprayer. After she gives her speech, click a painting to begin cleaning. You need to clean all three and recover the Shrinking Potion (1st painting) and the Crystal Key (2nd painting).
In Dr. Hare's dream, you have to dig down through the anthill with your axe, which you can also use to kill the ants (usually works). At the bottom of the second level is the Empty Sprayer, which you use with the turpentine from Captain Crawfish's dream when you clean paintings in Black Widow's dream. Once you have the Stopwatch (also from Crawfish's dream), you can go through the Binary Bard's dream to find the Diamond Drill, which lets you dig through the metal squares and reach Dr. Hare, who is down on the third level. His totem is just to his right.
