How do you clean the paintings and destroy the black widow's painting on Super Villain Island?

Answer 1

You need the turpentine from Captain Crawfish's dream (in the chest at upper left). The key to it is in the locker on the lower deck. (The key for the chest there is the red key above the door on the upper deck.)

You will also need the paint sprayer from Dr. Hare's dream. Dig down and avoid or kill the ants. 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).

Answer 2

You need the Turpentine from one of the chests in Captain Crawfish's dream, and the Empty Sprayer from the second level of Dr. Hare's dream. Once you talk to the Black Widow, use the turpentine and equip the sprayer. Click on each of the paintings to shrink down onto their surfaces, where you use the sprayer to remove all the red letters.

When all three are clean, you can use the sprayer on Black Widow's own self-portrait. She will be beating you up while you try. When the painting dissolves, it leaves behind the Paint Brush Totem.
