On SE its impossible to tame an Achatina so that should be removed from the QoB list. Also Ovis are really rare on SE. It's easier to find a phoenix. I think Ovis should also be removed since phoenix is removed.

achatina are tameable

ovis have 5 spawn areas on 2 of them i found 1 ovis (top left and green obelisk)

I went up to the achatina and I didn't have a taming option. They only spawn above max level in caves. From what I've seen they aren't tamable.

which level are yours? how did you tried to tame one?

here:

for default settings I was able to tame one just needed some narcotics

I thought it was a passive tame for some reason. I just tested it and you're right. You can tame them in the caves. Mine was level 26.
