Dorothy: “I think they have a few of the organs most animals have.”
Seamus: “I think they have a few of the organs simple animals, like worms, have.”
Nick: “I think the only organs they have that animals also have are the digestive organs.”
Valynda: “I think the only organs they have that animals also have are the organs they use for breathing.”
Brian: “I think they have all of the organs that most animals have, they are just a lot smaller.”
