After a successful year with the Dog Star Patrol, Mammoth Mutt decides to spend her vacation time on Earth. More specifically, the city of Metropolis. Relaxing at the Happy Doggo Groomer, the pink chihuahua gets her belly rubbed by a professional massage therapist. Perking her ears up, she hears people screaming off in the distance. Clicking open the red heart pendant on her collar, she pulls money out and plops it on the table. Running out in a hurry, the man just scratches his head and shrugs his shoulders.

“Time to get big!” Shouting so with a grin, the alien canine takes a deep breath and inflates into a huge round balloon. Bouncing off in the direction of the cries for help, she plops into the street of a burning apartment building. Exhaling, she deflates back to her regular self. Noticing a man in a ski mask on a motorcycle, he sticks an unlit molotov cocktail in a satchel, laughs, and rides away. He'll likely use the spare one soon. Meanwhile, the blare of a fire truck draws near, but Mammoth Mutt fears that they may be too late to save the people inside. Especially since her team isn't here, she must make a decision. What will the lone Dog Star do?

CHOICE A – The masked bandit must be stopped, or else more people could get hurt!
or
CHOICE B – The fire must be extinguished, or else these people may die!

CHOICE A – Sprinting through an alleyway to cut the guy off, she leaps at the bike as it swerves through a red stoplight. Leaping at the exhaust pipe, she bites it and begins swallowing its fumes. While the bandit drives as fast as he can, Mammoth Mutt inflates rapidly. Swelling up as large and spherical as she normally would, her buoyant body floats upward – taking the motorcycle and its rider up into the air.

While the man dangles from the handlebars, he keeps the bike revving at top speed. Inflating the chihuahua bigger than she's used to, her eyes bulge out while they float over a police station. Unable to withstand any more pressure, she lets go – making him plummet through the roof, into a jail cell. Comically, she whizzes off through the sky. Slowly deflating as she spirals around, Mammoth Mutt slams butt-first into the Happy Doggo Groomer. Ready for another massage, the alien canine blows smoke from her muzzle and lays back down on the table. THE END

CHOICE B – Spotting a nearby fire hydrant, Mammoth Mutt gets an idea. Growing both paws, she twists the nozzle cap off and sends the water blasting into the road. Striking a cute ninja pose, the chihuahua launches herself face-first into the stream – plugging it tightly with her muzzle. Gulping faster than she's ever drank before, her eyes widen as she inflates harshly fast. Becoming the worlds greatest water balloon, every single drop charges down her throat while she expands in the street. Getting way bigger than she's used to, Mammoth Mutt's paws all retreat into her morbidly sloshing body.

Unable to detach her mouth from the gushing water, she moans for help while realizing that she may indeed pop. Luckily, the firefighters have arrived. Unfortunately, her gargantuan body is slowly engulfing the hydrant and they don't want to go near the expanding furry bomb. Deciding to use the reserve water source in their truck, they start blasting the building with everything they've got. With a high-pitched creak, she can tell that her overtaxed flesh couldn't take much more pressure.

Nearing the size of three whales in the street, she's almost as big as the apartment itself. Finally, after the most exhausting drink ever, Mammoth Mutt explodes – extinguishing the fire in one single tidal wave. While the firefighters cheer for the strange dog, she lays there with a bandage across her abdomen. Pawing all over her sore belly, all Mammoth Mutt wants now is to head back to the Happy Doggo Groomer. THE END
