Infested Tree

There is an exit west from the Feed Room (Fr) but I couldn't fit in there. There's also an exit south from A Curve in the Tube (Cu) but I couldn't fit in there either. The water is not fit to drink at the sleeping roots. North from The Ledge (Le) is The Long Fall (Ff). If you're not flying this is a death trap. If you are flying try to resist the urge to fly down to the Bottomless Pit (Bp) as this is always a death trap.. You can go south from the Sunken corner (Sc) to the Dusty Slide (Ds), you can't go north from the dusty slide to come back. Similary you can go from the Small Room (Sm) to the Air Room (Ai) but not back again.
