The Retro Tube TV is a furniture item in Nintendogs + Cats that can be bought from Modo Home for $300 in all versions once it is unlocked with 2,600 Owner Points or by playing 13 days. It can be placed in one of the four corners of your home. It depicts puppies and kittens in the Mario style home, wearing Mario-themed hats. Dogs may watch the TV, and even bark or howl at it.
3DS: "An old tube TV. Smacking it on the side won't improve the reception."
