Mossy has a tutorial on getting the g-ghosts acheviment on their channel, Moose-shower. The couples therapy one, you have to talk to Moose in Sunclan until he asks you to give Nightlight a pink tulip. After doing so, talk to Moose. Then, talk to Nightlight again and answer "yes" to her question. Next, talk to Moose and then talk to the tortoishell cat in the tent (I think her name was Fleetshine??) And then talk to Nightlight and then talk to Moose.
