My DD loves all the AG animals and she also loves her MG, so Argos was a no brainer for her. I also think the animals are way over priced, so DD bought Argos, Nutmeg, Coconut, Talto, etc with her own money.
Argos is really cute and is a unique stuffed animal. I don't think you could find one like him for less and I wouldn't know where to look. I do think he is an essential part of MG's world.
