Botting Jon to give him a Take 10 on his Survival roll.
Jon notes what he initially thought to be a dirt road is actually the trail of some creature. Whatever it is is legless, sliding over the ground and apparently destroying everything organic in its path. There isn't much left here so close to the blast, but the trail has been swept clean of any organic material. It seems to wander erratically before straightening to head nearly due northwest toward the hills.
Magnus/Tuboo returns a short time later, dragging some sort of vegetable matter with him. It's about a foot in length, bulging out towards the middle like a developing pea pod, but clearly some type of fungus to Jon's keen eyes. It trails a number of "roots," which Tuboo/Magnus is using to drag it along.
