Boundless, bribes for creatures

Sorry for asking a lot about boundless, but i think it’s a large and expansive game, and i really like finding things, but one thing i really can’t find is how to bribe certain animals (like leupais and amplibaenes) so could any of you guys help me with that?

Boundless was pretty unfinished on both canceled versions. It is likely that the option was not fully functional on most most monsters, but it is likely you also need a mound.

I did get one, but i still couldn’t find out what they wanted from me.
