A list of fan-made Challenges to make a Niche tribe more interesting. Please add your own ideas! (Make sure there isn't one like it already first) (Some of the smaller challenges might be better to combine (play several challenges at once).)
A very simple but hard challenge-you can't ever use the Mutation menu. If your creature has Short-sighted eyes and you want to breed them with a regular eyesight mutation, too bad.
It's simple, but hard. You can never, ever look at your Nicheling's genes, including the Family Tree, since their genes are shown there. (Optional: Yo can open the Family Tree, but you can't look at their genes. Only do this option if you trust yourself.)
Every creature in the tribe must have at least 2 children in their lifetime. (This does not count Rogue Male children.) If a Nicheling is infertile, they must be sacrificed. (Drowned, killed by Bearyena/Ape, starved, etc)
Your mission is to have the strongest creatures possible. You must also kill and destroy everything in your path (not including Friendly Bearyenas, because you'll need them to become stronger). Examples of genes you want: Armored Body, Big Body, Bearyena Snout, Bearyena Claw, Hammer Tail, Claw, Sabertooth, etc.
The aim of this challenge is to collect all of the ancient genes (mammut foot, sabertooth, etc) or create a lookalike creature to your specific requirements (down to pattern, eye color, etc) using one or more of these ancient genes. For example, you could try and create a mega creature that has all of the ancient genes actively present, or breed a creature that looks like an extinct animal or animal that uses an ancient gene (reindeer for megaloceros horns, Sabertooth tiger for Sabertooth fangs, you get the point). The challenge must obviously be done on a mountain/snowy island that enables you to get the genes.
The Globetrotter Challenge is a fast-paced, spontaneous challenge recommended for semi-fully experienced players that want a casual, fun challenge to do. The goal of the Globetrotter Challenge is to reach the Home Island with 1+ creatures that have Home Island immunity within the quickest time possible. How many days you want to generally restrict yourself to per island is up to you, but I recommend 25-30 days per island, depending on how big it is. I suggest creating 1-2 new generations per island (fast paced). This challenge is in story mode. I also recommend, when still on easy islands, to gather as much food as possible while it's easy so going through the hard islands is easier.
Divergent Evolution Challenge
The aim of the Divergent Evolution Challenge is to create two sub-groups of nichelings (e.g one group has all red, fighting nichelings, one has all white swimmers/fishers), all from your starting Nichelings. Story mode is not required for this challenge. Wanderers are allowed into the tribe, as they may carry the genes you want for a sub-group, or could determine what the group's genes may be, but each wanderer taken in must only breed with one group. If you want to make it harder for yourself, then don't allow nichelings from different sub-groups to breed, even if you are desperate for opposing immunities or other genes. The challenge is done once you have two clearly distinct breeds of nichelings.
Wolf Conquest Challenge
The Wolf Conquest Challenge/Pack Conquest Challenge is based off of Seri! Pixel Biologist!'s Pack Conquest Series. There is no strict goal of this challenge, but it is necessary to attempt to breed as strong and carnivorous creatures as possible (if a creature is born a herbivore, thats fine, but no berry-and-nut-collecting genes should be put in the mutation menu, only defensive and offensive genes). In Wolf Conquest, every generation of creatures should have one-two breeding pairs or breeding groups (one main breeder, many others that breed with the main) and all other creatures focus on acquiring more food and other stuff. Breeders have the Alpha rank. Another rule in Wolf Conquest is that babies born of rogue males, wanderers (depends), or very poor genetic creatures are inherently slaves from birth, and are only to collect food and must not breed. They have the Omega rank, and will (if it happens) starve first. All other creatures have the Beta rank.
In this challenge you must only have one creature (with one exeption). When you start, you must immedietely release your male. You can have babies with him still, but you have to release them as soon as they become adults. However, you may pick one of her daughters to be the heir, and once she becomes an adult, you have to make her wander away from her mother like her siblings, except you're controlling her. Once her mother passes away, the new heiress must find a male to carry on the next generation.
Hyena Pack Challenge
With the Hyena Challenge, the main aim is to set a social hierarchy similar to that of hyenas. If you're in story mode, move to a bigger island as soon as you can. Once at the island, set Eve as an alpha, and Adam as an omega. If you're in sandbox mode, just skip to the rank changing. Once you have had a bunch of kids with your starters, pair up the genetically compatible ones into couples, and mark the couples with gem colours/combinations. All females born are alphas by default, and all males are omegas. As hyenas are strong predators, and were the inspiration for the beareyna's design, hybrids are suggested genes to incorporate to your tribe.
-There will eventually be multiple packs within your tribe
-Each pack has their own gem/colour combination
-Wanderers and rouges have a separate gem combination, and are betas instead of alphas for females.
-Babies are given the combination of their birth pack
-Males move to a different pack when they gain 3 gems, and keep their birth pack combination
-Female stay with their birth pack from birth to death
-Males and females with the same gem combination may not mate, no exceptions.
-Females aren't allowed to breed until their most recent child/children attains two gems (this can include the baby being born to a mother who's child will grow to 2 gems on the same night).
-Females are hunters, taking down bunnies, moles, and predators while males gather the meat and berries
-Females are allowed to live out their natural lifespans, but if a male creature has 5 days left of his lifespan and hasn't taken at least 5 days worth of damage, he must be banished and killed.
Females first, males second
Within the females, rank is determined by strength. If two females have the same amount of strength, the older one has a higher ranking. For twins with equal strength stat, flip a coin to see who ranks higher. Juvenile males and females rank just behind their mother. With this, generally the strongest and/or most "beautiful" females have top mating priority, and males who are oldest.
Within the males, rank is determined by who came into the pack first. (Challenge taken from here)
The Amazon Challenge is one of the most well-known, attempted, and most likely failed niche challenges that is widespread. The Amazon Challenge is set in a jungle, all of which can be played in (an easier one is suggested until you're confident with playing a hard island), and is like pack conquest, where all grass tiles should be cleared before moving to a new jungle island. In the Amazon Challenge, females are born alphas, and males omegas, and have according social ranking. Generally, there will be one lead female who rules and dictates the tribe and their actions, and she will banish males from the tribe once they reach 3 gems of age. The males are intended to go through a trial time to see if they'll survive the jungle, and once they appear again, you can choose to let them in again and breed with females as a beta, or kill them. As a suggestion, write down all the nichelings for each generation and pair them off for the future before releasing them, so you'll know which ones to kill or take in. In the tribe, you are allowed a maximum of 1/6 of your tribes size in slave males who only collect and don't mate to keep (e.g. If you have 21 tribe members once all the nichelings of a generation are born, that means you can have 3-4 males that you wont release and will keep). It is also a good idea to almost corner your breeding males when you release them, because I found out the hard way that they like to disappear forever if you don't sometimes.
The goal of the Mimic Challenge is to have at least one recreation of every non-nichling creature in your tribe. For example, your rabbil creature would have long ears, white fur, black eyes, double runners leg, ect. Animals such as crabbits and fish can be left out, as there are no genes similar enough. The mimics must look as close to the original animal as possible. For example, your rabbil cannot have genes like spiky body or cracker jaw. For an additional challenge, your creatures can't have recessive genes that are not the genes it needs. For example, your rabbil wouldn't be able to have recessive webbed hind legs, even if the rabbil had normal hind legs.
