I choose the mangrove option and watched as my floor changed, mana is amazing it takes but a moment of time to do years of normal growth and before I can admire everything it's already finished. I'm over the moon, it looks like home.

The space closest to the stairs looked like beach but the deeper into the floor you went the water level gets deeper and the less it looked like a beach and more like a forest that has been sunken in time with a lot of higher dry areas, perfect for relaxing in the summer.

I had been to a mangrove forest not far from my house in my last life and I found it very relaxing. I couldn't wait to see what options I would get for monsters.

[Congratulations on choosing your third ecosystem. This ecosystem is incompatible with your current location, to make up for the shortcoming of monsters please choose one of the two groups below. Hint. If you spend dungeon points you may buy monsters you did not chose now at any time in the future.]

[Mangrove choice one. Algae, Invertebrates, Rats, Assorted predator fish and prey fish, Dolphin, Various non venomous snakes, Green tree frog, Mosquitos, White Ibis, Great Heron, Osprey, Great horned owl, Green turtle, Striped skunk, Mink, Fishing cat, Grey fox, Marsh rabbit, Proboscis monkey and Crocodile. All choices have some form of mana.]

[Mangrove choice two. Algae, Invertebrates, Rats, Assorted predator fish and prey fish, Various non venomous snakes, Green tree frog, Mosquitos, Limpkin, Yellow crowned night heron, Peregrine falcon, Barred owl, Raccoon, Otter, Bobcat, White tailed deer, Black bear, Manatee, Dugong and Alligator. All choices have some form of mana.]

My mind is overwhelmed with all the choices I've been given. I guess I hadn't realized how many animals lived in such a small area. I see lots of repeats again, I'm assuming those are necessary for it be called an ecosystem.

I wonder how many more ecosystems I have to get because I can make my own. It shouldn't be too complicated right? Well that's a problem for future me. I know one thing for sure I won't be summoning any mosquitoes for my floor. I always felt they were useless. The frogs are just gonna have to adapt if they wanna stay. I take my time going through both of my choices and I think I'm going to have to go with option one this time.

I chose option one and I followed the same order I did last time and started with filling my mangroves with algae so my invertebrates would have plenty to munch on and then I looked through what my options were and I was surprised to find a lot of choices.

Moon jellyfish, Upside down jellyfish, tree crabs and fiddlers crabs along with barnacles and horseshoe crabs. I was impressed. I summoned six of each and let them explore the floor without any predators. Then I took it upon myself to start making my figurines for my altar for the third floor, I had lots of figurines to get started on if I was going to keep the same pattern going.

Apparently it's really easy for me to lose track of time when I get in my zone, so now it's time to summon some more monsters for this floor. I check out all my fish options before I summon six of each, red snapper, black snapper, cubera snapper, lane snappers, mangrove snappers, mutton snapper and midnight snapper. So many varieties of snapper!

I summoned some grouper and tarpon and some cichlids I even summoned two gars to help keep the populations down. I might have to figure out how to make fishing poles for my delvers. I'm sure they would be surprised and delighted.

I had to make a small island for my table to sit on so my metal table wouldn't rust, does silver and gold even do that? Then I went back to finishing my altar because that needs to be complete before I can come down here, it didn't take long I had just been distracted making my figurines.

With my new altar ready, I flattened out the divot I had been sitting in and disintegrated the cage around me and just left my figurines this time and floated down the stairs towards my new altar. I enchanted my new cage with a strengthing enchantment so it would be harder to break, safety first you know. I'm pretty sure I've grown since I've moved down to the third floor. Which delights me, the bigger I am the more mana I have to summon my monsters.

I decided to check out my other floors and see how my wolves have been coming along. I was quite surprised that my older wolves had made dens for the new wolves to adapt to the cold, and it was working. Their fur was getting thicker, not necessarily whiter but lighter than the sandy brown it was before. I could see that the three females were all pregnant so I was excited for the results.

I don't think they would ever actually be unseen like the other wolves but that's ok maybe the system would register it as something new when the change or evolution was complete.

The first floor was still a frozen wasteland with monsters scattered about and I was confident it would be a challenge for anyone who ventured in. The number of monsters were stable except for the voles which I felt should be named snow rats.

I checked in on my second floor and it was just wonderful, almost the complete opposite of my first. Warm, cheery and life everywhere. My monster numbers were doing great and I was really happy with my herd of zebras and gazelles, still no honey badger baby but it's ok I have nothing but time. Time to focus back on my third floor I had a lot of monsters to summon.

I looked at my list and I chose to summon eight pairs of monkeys and let them take to the trees, and then I summon four pairs of green turtles and leave them close to the stairway because I'm not sure where they flourish the best. Then I summon six pairs of rats and try to ignore what direction they scamper in to.

I decide to bring my attention back to my little island. I have an excellent view from my spot, I may have be been a little extra and made a really tall island so I could over look my kingdom. Of course right at this moment I notice something is killing my voles on my first floor. I finally have another intruder.

It's a god damn polar bear and it's fucking huge, I'd seen a polar bear at the San Diego Zoo with my grandma once when I was a kid and this one couldn't compare at all. This one had to be at least twice as big and after just a glance I knew it was vicious from the way it tore apart the voles.

I sent out a swarm of native foxes and a pack of wolves, I wasn't ready to send out my new types yet. The polar bear fought with my monsters for a full twenty minutes before it came crashing down and my wolves howled in victory. I had lost three foxes and two wolves to the polar bear but I didn't take the initiative to summon a polar bear for my first floor. That was not the type of challenge I wanted just yet.

But it did give me a lot of dp, a whole one hundred and fifty. I decided I didn't need to summon any monsters to replace the ones I'd lost as the population would come back up on it's own. I loved my dungeon, it's so self sufficient.
