Base: Sirius' Dog Dome

On Mars, Sirius lives comfortably in a doghouse built by his owner. He has everything he could want, from his basic needs like food and water to his favorite plushy, Ursa. When he wants to play, Sirius goes outside and chases a tennis ball launched hundreds of feet by the specialized Star Shooter fixed to his dome. After tiring himself out, Sirius can curl up for a long nap in his bed.
