Investigate the Spawning Glen in Zangarmarsh, and then report back to Watcher Leesa'oh at the Cenarion Watchpost in Zangarmarsh with your findings.
Investigate the Spawning Glen
We need to learn all that we can of the sporelings at Sporeggar and their relationship to the creatures around them. One way to do that is what I'm doing; passive observation while making a note of their interactions.
I need you to head over to the Spawning Glen to the west. Investigate the whole area and then return to tell me what you saw.
