Foolish

This desolate biome has been left in shambles after a striking amount of radiation. Hence, there is not much life in this biome- and all the life which remains has become mutated. This biome is the only Stellar Hollow biome where you can find Radium, as well as its liquid counterpart. Liquid Radium is not to be trifled with! Coming into contact with it damages you, decays your armor, and pulls you further into the substance. Additionally, Corrodiators, noisy flying mobs made of Liquid Radium, can spawn. The Wasteland's sub-biome, the Irradiated Undergrowth, has turned into a strange forest of mutated trees and fungi.

By far the Stellar Hollow's most lush biome, both in flora and fauna, the Overgrowth is a thick cluster of trees and giant flowers. The mobs here seem to have become one with the foliage, from the miniscule leaf insect-like Leafids to the gentle giants, the Amblers. One peculiar mob is the Fruitling- a small passive mob which comes in 6 different flavors, each yielding different effects. The main mob, however, is the Florin, a rabbit-like creature which defends the Overgrowth from hostile mobs. Florins may drop their seeds if bone-mealed, allowing you to build your own Florin army.

This striking biome's main characteristic is its fiery trees, which, despite their appearance, are safe. The mobs in this biome, like the Spitfire or the Brander are somewhat elusive, but will drop valuable resources essential for this biome's Stellar weapons.

A direct parallel to the Overworld's jungle, the Storm Jungle has a statically-charged air. Even the Acacite boulders found around the biome produce a small amount of Redstone energy! Under the towering trees, you will find a wide array of mobs, and some of them can be tamed. The Buzzket, a small, cricket-like mob, may have a small amount of health, but it will fight back anything that attacks it by paralyzing it. It can be tamed with Lightning Reeds, but it won't follow you. Another tameable mob is the Torrent- these dragon-like mobs can be tamed with a few Storm Apples, after which they can be used as powerful flying mounts!

As the name suggests, almost everything in this biome is a shade of red! Scarlet Fields biomes are often reasonably small, and they have a more rare boss structure, so it is always worth exploring them. If you find one, be sure to tame a Sanguine, an ostrich-like mob with a heart-shaped head, simply by riding it for a while, just like a horse. Sanguines don't require saddles to ride, jump high, don't take fall damage, and make for a trusty steed while exploring the Stellar Hollow. Or, if you're hungry, they can be killed for meat. This, however, will cause the whole pack to go into a defensive mode!

This biome is by far the most dangerous and unwieldy biome to explore. Parts of it are submerged, swarming with terrifying Horrendons. Most of its other mobs have been exterminated by the Kappas- the rulers of the Miserable Mire. Everything in this biome will attack you on sight!

Perhaps the most curious biome of them all, the entire Sacilite biomes are made of Sacilite, a living stone. Sacilite takes multiple forms, from "trees", to even mobs, some of which resemble animals and can be eaten (Sacilians). Most of the Sacilite mobs in the Sacilite Bloom biome spawn in groups around large Sacilic crystals. The Sacilite Canyon, a rarer biome, has mostly dead Sacilite. Tremors, quadrupedal, bat-like creatures, seem to like it there, and can be tamed with a lot of Tremor Treats. When tamed, they make powerful battle mounts as they can unleash heavy attacks from a distance and they can also glide from high places.
