I assume you're referring to Bunnies Lair.
It is planned that Nishy would mind switch with more fapet types visiting their according lairs.
"speak to them" : generally speaking, talking with them is only available while mind-switched. But their Queen should be able to talk aswell, hopefully
"tame them" : that's a maybe. Most of the times you'll meet those chars outside of the lair (like the hoodie 2 colored hair bunny girl, Yuri if i'm not mistakening, later seen 'working' with barmen on the beach (in free mode's summer event) ).
