Again, these drops haven't been confirmed yet. Just some fun speculation. :P
- Zhu-Gon the Sour (possible drop Skunky Alemental)I realize that the PTR Pet Journal lists the Bloodcove Droplet as a drop from "Bloodninja McBlood", but there's currently no mob on the isle by that name. It's possible that it may be a drop from an NPC by that title, but it just seemed to fit that a pet like the Bloodcove Droplet would drop from a mob with similar looks.
- Leafmender (possible drop Ashleaf Spriteling or Dandelion Frolicker)
- Spirit of Jadefire (possible drop Jademist Dancer)
- Emerald Gander (possible drop Azure Crane Chick)
- Bufo (possible drop Young Gulp Frog)
- Imperial Python (possible drop Death Adder Hatchling)
- Garnia (possible drop Bloodcove Droplet)
Those are the best fits off the top of my head. Hopefully we'll find out where all the new pets come from soon!
