Since I already covered Tracker's Jeep and Everest's snowplow, I won't be covering them here. But really, Ryder must either be super rich or super smart to get these vehicles for the pups (theory coming soon¿?), so I'll cover them all one by one, starting by Marshall.

Fire Truck
Marshall's puphouse is probably the most interesting, since it's a hybrid of two completely different types of vehicles. But the vehicle that Marshall is most commonly known for is his fire truck.

The most commonly used object used in his missions a tall ladder. It also has a hose, which I don't think he ever used in any mission (kinda weird for a fire-FIGHTING pup). But other than that, the vehicle number is 03 and it got repainted in Season 3 for jungle missions.

I think this vehicle'd be more exciting if Marshall was ever involved in a fire-fighting mission, requiring to use both the ladder and the hose. But it doesn't look like that's gonna happen anytime soon. It's still a golden vehicle either way.

Ambulance
I don't think this vehicle had a specific story to it, but it just kinda appeared in Pups Save Jake. It's large enough to fit an entire human inside with room to spare.

The amulance itself contains a stretcher, a thermometer, and a stethoscope, shown in Pups Save a Show, and were first shown while Marshall was caring for Cap'n Turbot and Chase.
And since it's really just the same vehicle as the fire truck, it's vehicle number is still 03.

I personally find this vehicle to be very appealing, not only because of its colour scheme, but because emergency missions are tense and exciting. But because they can't make really make harsh scenes because of the show's demography, so they replace all those possibilities by calling Marshall to check if 'tHe pEnGuinS hAvE a HiGh TeMpErAtUrE'. What a shame.

Fire boat
In season 4, a new building called the Beach Tower was introduced. With it, each pup got a new vehicle, Marshall receiving a fire boat. The fire boat was introduced in Pups Save the Sharks, and it has the shape of a speedboat.

The boat is equipped with emergency lights and cannons (no, they don't shoot cannon balls). The cannon has a dispenser on the top of the boat, where it then shoots it out through the cannon.

Surprisingly, I see some potential in this vehicle. And no, not the pointless cannon. I'm talking about the speedboat itself. What if there was a chase scene with Mayor Humdinger stealing the Sea Patroller, and it was up to Marshall to get it, since his speedboat was the only vehicle that was able to cope with the speed of the Sea Patroller. But hey, that's just an idea.

Well, those are my thoughts on Marshall's vehicles. Let me know what topics you want me to rant on next! Also, Merry (late) Christmas!
