Red Svarpain
As you take the left turn in the forked road, the trunk of a big tree comes into view. It's branches reach high up, obscured by the rest of the plantlife. As you gaze up in wonder, you spot an unusual bright red between the leaves. And sure enough, the ribbon of red moves, slithering down through the branches and down the trunk until you come eye to eye with the red svarpian.

Quick! Charm it!

Inch your way around the big tree and continue on.
Or, decide you've had enough and head back to the Hollow Tree.
