Thanks to the efforts of others in the 9.1 thread
here, the following have been confirmed tameable in the upcoming patch, assuming nothing changes:
- Acidmaw Scorpid (Has missing assets)
- Amber Parasite
- Crystalline Scorpid (both versions, has missing assets)
- Dreadfang Slitherer
- Dreadfang Slitherer
- Kovok
- Mist Hound
- Ohgan (Uses a new model not shown on petopia!)
- Rageface
- Raigonn (full form, broken form unavailable)
- Riplimb
- Shalebiter (retains its name for some reason)
- Skorpyron (Has missing assets)
- Venomous Spiderling (version found by the first trash pack in the room)
- Volatile Scorpid (Has missing assets)

I openly admit to finding bugs and exploits so they can be reported asap and get fixed. You might have seen some of the fun hunter pet side effects posted here in the past.
I will never share how to perform exploits. The only ones who know are those I personally trust to help get things fixed.
