In the lab, a few scientists sit there and drink coffee or talk. One of them, as per protocol, presses on the large, unmissable red button on its one platform and the thick metal sheets that cover the windows slowly descend into the ground. Showing off the vast diversity in life in this hell on, or in, earth.
Godzilla is down here to, since Hollow Earth has a high concentration of radiation than earth, and is resting on a elevated platform, laying on his belly as his dorsal plates are a good spot for a flock of Leafwings to rest on.
Kong is with Suko, teaching the young ape some ways to defend himself from other titans and monsters. With Suko just listening. And Ramarak (the large Skullcrawler) is watching Kong with a burning hate.
4 Skullcrawlers are viscously ripping apart a killed Sker Buffalo, eating it in a ravenous manner. There are also a pack of Death Jackals watching, waiting for a time to grab some meat.
Ghidorah was leaning against the mountain, about 2 miles away from observatory room, and talking to with his own heads. (Left head is Ni, middle is Ichi, and right head is Kevin). With Mothra and Shimo just quietly resting in their own areas, with Shimo on the opposite side to Godzilla on the large river, and Mothra in her nest.
Rodan is in a massive valcano nearby, which would also have a fee Larva Turtles. There is also the Tiamat, coiled around her own serpent body underneath the water, resting as she also takes in the high levels of radiation.
In the lake itself, a large Siren Jaw has its mouth open as its body is hidden in the depths of the muddy lake, hoping an animal can think it's a cave. A mire squid is also there to, sleeping with its octopus body camouflage as it hides from any eyes.
In the forest that surrounds Shimo, you can see the hidden Spore Mantis that has its body hidden and safe in a tree trunk. But in the patches of bamboo, the 20 meter tall Mother Long Legs stand still as they wait for a stupid human.
And Doug, who is lazily a sleep on a large rock.
