Not quite the same but related, my plantsim who is married to Paka'a and lives in Mua Pel'am, while I was playing him would go around every day cleaning up the ecosystem to make it nicer for his husband. Then when I went back to Mua Pel'am with a different household, he turned up as an "anti-environmentalist" trying to have a fight with my next played sim! They really need to have some restrictions on which sims are chosen for these roles.
I don't allow mounting fish or cooking with them in my saves - since "bowl 5 fish" has never worked I cheat code the aspiration, and any fish I'm not keeping in my own collection I sell for someone else to keep as a pet. Seeing Paka'a have an early morning chat with a fish in a Gumber is rather endearing.
