The group then spotted Marinopolis upahead. The buildings were made of stone with many windows on each side of then all and the city itself was surrounded with what looked like an enormous glass dome or an enormous air bubble.

"That's Marinopolis!", said Dytoha with pashion, "Don't about breathing while in the city, the dome is full of air and lots of it!"

As the 9 trecked towards Marinopolis, they were suddenly ambushed by a swarm of little, purple-colored Fish with Lamprey-like teeth and fins resembling knives.

"Look out!", cried Dytoha, "Those are Vampire Fish! Nasty little parasitic vermin!"

The 8 heroes quickly made force field with their combined powers to keep the Vampire Fish at bay. It worked and the little blood-suckers retreated into the gloom of the deep ocean.

"Better look out for those guys", stated Rainbow Dash as she and the rest of the group continued for Marinopolis.

"Got that right", replied Twilight, "I've had enough little parasites try and attack me lately"

The main entrance into the domed city was an odd-looking, door-like structure.

"Not to worry", said Dytoha, "This entrance is made of extremely thick bubble, so clearly nothing can break it open"

The group followed him through the doorway. As they passed through, it was as if they were ghosts going through solid walls as they moved through the bubbled entrance.

The group then deactivated their spirit armor and found that their was plenty of air to breathe inside this domed city. They also saw Hippocamps everywhere, moving on the ground by using their Dolphin-like tails to slither like a Snake while their hooves were hel up in the air for balance.

"Hey look!", exclaimed Dytoha as the Hippocamp named Dalgor (as you may remember from chapter 2 of this story) was approaching with his pets, "It's my adventurous cousin! Dalgor! And his pet Lizard Lobsters, Tooji and Mofo!"

"Why are their land Creatures behind you Dytoha?", asked Dalgor as soon as he reached the Dytoha and the 8 heroes, "Are they spies?"

"No", repsonded Dytoha, in a rather annoyed voice, "These here land-walkers are gonna save us from the Deep Water Steeds"

"Are you sure that Salango and Ihari are not our protectors already?", asked Dalgor.

"Who are Salango and Ihari?" asked Griffy.

"They are a male and female Hippocamp who think they are destined to be the best protectors of the city", responded Dytoha, "However, they more often go out on romantic dates with each other, since they apparently fell in love quite recently"

"Are they all still here?", asked Applejack.

"No", replied Dalgor, "Those two lovers actually disappeared recently and have not reported back for days now"

"We better get to saving the ocean now", said Spike and with that the group activated their ocean-adapated armor and abilites and went otuside the city for their underwater quest of a few mysteries to solve.
