Mr. Grouper: At the top of the Arctic, is the North Pole.
Deema: There's a pole up there?
Mr. Grouper: There's not actually a real pole up there. The North Pole is what we call the very tippy top of the world.
Mr. Grouper: Arctic Rangers, Arctic Rangers. Please respond, over.
Molly: Arctic Ranger here, go ahead.
Mr. Grouper: A narwhal needs your help.
Deema: What's a narwhal?
Nonny: A narwhal is a kind of whale that lives in the Arctic.
Deema: Look at that crazy horn.
Nonny: The horn is actually a really long, twisty tooth called a tusk.
