File:Fur Fighters - New Quack Subway (Level 4 - Unused Level)

Description
Screenshots and comments: http://furfighters.xemnas.net/test.php

This is an unused level that can be found in Fur Fighters: Viggo's Revenge. Unlike the other unused levels which were used for testing, this is a fully playable level that has been left out of the game. Needless to say, this level is not normally accessible, even through the level select cheat.

The level is one of the earliest known, since it even incorporates an item which would later never be used in the game - A 25 Token nugget.
