Skeeve gathers the coins he can find and hurriedly grabs the book. Nothing is hidden; all will be divided later.
Now, Skeeve wants to use multiple force walls. While they only take one to destroy, they should be sturdy enough to withstand the gunk. He creates three in the shape of a "U" (if looking from the top). They are about six inches from the bottom. He then creates a fourth next to the bottom of the "U". He then moves the fourth one away from the bottom of the "U". In the end, he should have a box that they can then use to only have to wade through six inches instead of however many feet. However deep the slime is will determine how long each of the walls can be. If needed, he can then reshape Stick into a rake to help with the sifting.
This will get him filthy, anyway. However, when done he simply uses Spell-touched to clean off.
Oh, yeah, he also heals everyone back up.
