This level uses the "brick" texture which can be found in the Wonderland Nutters archives. Download the archive. If you're lazy, you could just not download it and use the default wood theme, but the level is much more pleasing to the eyes with the texture. Please use it.
You shouldn't have too much trouble with this one.
I made it with 42 seconds to spare.
