just wondering where the secret warehouse is becuase i seem to hav forgotten where it is or are u talking about the rat cave?
the secret warehouse is where bigfoot is. theres a stairs just before the door to the furnace room and theres a pile of boxes, once youve built it you go up to the boxes and they lift to reveal some stairs, go down them and you should be in a room with bigfoot and a fortune telling machine, hope this helps.
