How do you get Dr. Hare's totem on Super Villain Island?

The Golden Carrot Totem is at the very bottom of the anthill where Dr. Hare is being held captive. This is likely the last one you get, because you need an item from another dream, that also needs an item from another dream.

The first two dreams you go to are Captain Crawfish and Dr. Hare : you need the turpentine from Captain Crawfish and the Paint Sprayer from Dr. Hare in order to clean the paintings in the Black Widow's dream.

To get the sprayer, dig down through two levels of ants (you can Dodge them or try to kill them with your pickaxe). The floor of the level is metal, so you can't go down any deeper.

Later, using the Stopwatch (also from the Crawfish dream) lets you go into the Binary Bard's dream where there is a Diamond Drill. You can use it to break through the metal squares and reach the bottom of the third level, where Dr. Hare is being held. To his right is the block of squares that hides the Golden Carrot totem.
