This is the first time we've seen Nemo's dog, a guard dog named "Sullus." We learn that "sullus" belongs to a "guard dog" , and that the dog's name is "Atsuya." We also learn that atsuya's "atsuya" is "a pant ba- thump pant" . This is a major departure from Nemo, who used to be a "paternal ba-putter pant." Now that he's got a dog to protect him, Nemo is "stunned" by what he sees. He's also horrified by the sight of Atsuya inside him.
