When Joe asks the Kangaroo if it gets ball off of roofs in its natural habitats, close-captioning reads "rooves," but the proper spelling is "roofs."
Armadillo: Uh, oh, it's another animal. Watch how I curl up, so I can hide.
Joe: Enjoy your snack, Giraffe.
Joe: Hey, joey. I'm a Joe.
Side Table Drawer: Hey, Joe. Have you ever gotten your notebook from a goose?
Joe: The animals are inside our house!
Joe: Um, welcome to our house, Giraffe.
