Annoying Dog is one breed with Akamaru, but more fluffy, with shorter tail and absolutely white. You can meet this unpredictible creature everywhere in the Underground, even in those places where it couldn't be by common sense (excepting the Ruins). It sometimes seems that it uses teleportation. It's very friendly, naive and playful, like all puppies. But unlike other small dogs, it doesn't have a sense of fear. All monsters call it "annoying", because it always sidles up to everyone who meets to play with them and be petted. And it doesn't leave you alone until you do what it wants. However, if you were very rude with it, it can turn wild and become a big red dog, and, trust me, you'll have a lot of problemes.
