Dear Laura,
Please! Help! My Norns are eating nothing but seeds, they are able to move their hair up and down, they are building nests from grass, and they are laying eggs without mating!

Dear Sad Hand,
Your Norns have obviously become avid twitchers, converting the Norn Terrarium into an aviary. I'm afraid that drastic measures are called for, as this fixation is far too advanced. To rattle this gigantic bird cage, introduce them all to the Neko Ettins. Their feline features should cure your Norn's obsession with our feathered friends... And watch out for any unexpected 'missiles' from above; cats scare birds.
