Definitely get Erik. I have him in my town and I adore the little cutie. Everything about him is adorable; from his lazy personality to his cute muzzle to his innocent eyes to his house to his catchphrase. He is my third favorite villager of all time right up there with Kyle. Erik is definitely the right way to go <3
Also, keep Freya. I don't have Freya in my town but I have the other snooty wolf, Whitney in my town, which is close enough. I love all the wolves, they are really awesome. And honestly, snooty wolves just really bring out the personality. You wouldn't expect a big bad wolf to be snooty, but Freya further proves that it can definitely work. <3
