Green Buncher taming is borked?

[Violet Echoes]

I must have killed hundreds of these bananas by now, my team is crazy over leveld and I have thousands in money but still not a single tamable banana dude for the quest. Why, is there a trick I am missing?

Just piss poor rng, spent huge amounts of time trying and failing to tame somethings myself.
