Green Svarpian
Before you the path splits, one side continuing on to the west, keeping the darker areas of the swamp to your right. The other fork heads just there, going deeper into the marshes. As you stand there, deciding which fork to take, a dark green svarpian slithers into view.

Hurry! Grab it and don't let go!

Keep on heading west.
Turn right and venture deeper into the marshes.
