Niffler Physiology And Behaviour
Mun Note: This is 100% my own work based off my own research into various animal habits and my own ideas for how my niffler works, thinks and operates. While folks are welcome to use this if they wish I do ask that you get my permission first, and absolutely do not reblog this post as I would rather not have it floating around outside my little space if possible ❤
Food & Hunting:
Nifflers are omnivores. They are particularly fond of barley, maize, oats, and any berry they can get their wee paws on. Those who have access to human markets will often show fondness for apples, peaches and pineapples as well.
Their primary source of nutrition however comes from crabs, crayfsh, earthworms, fish, frogs, large insects, and shellfish. While it is possible for nifflers to take on small mammals (as large as rabbits, in fact!), their bills and clever paws are better built for holding on to slippery prey and cracking open shells.
What is more, nifflers prefer to maintain a healthy social dynamic with land animals as their burrows and latrines tend to interconnect with badgers more often than not. Nifflers are quick and slippery on land, but are far faster in water and almost impossible to catch when hunting without the use of magic.
Gold, Jewelry, & Shiny Things:
Nifflers have an incredible attraction to shiny things, and much like their fastidious badger neighbors are very keen on keeping such items highly polished and well cared for.
If something is dusty or spotted it is very disgraceful to a niffler and will be immediately rectified – it is for this reason that they consistently hunt for forgotten shinies, as there is nothing more disappointing to a niffler than neglected treasures.
However, on their hunt for things to polish and hoard, they do note when things are well loved or worn. These pieces in particular they polish up their very best before putting it somewhere almost enshrined for it’s true owner to find again.
Though they also have the habit of taking anything shiny someone happens to be holding for inspecting and cleaning, nifflers generally make an attempt to bring these things back. Sometimes they forget – or don’t bother. It all depends on how rude one gets when something is being borrowed for a cleaning!
By that standard though, new things, such as jewelry in shops, are considered free game because they are just sitting about unattended and unloved. This is often what makes them so very unmanageable – to a niffler, it’s just borrowing, or plain being helpful – but to most people, it’s a rather notorious predilection for theft!
Social Behaviour:
Nifflers are incredibly social creatures. They live in underground burrows that are passed on through the generations, work together to raise their young and even invite other species into the sett when winters are particularly tough. They are known for making friends with their neighbors, putting them very at ease with badgers, foxes, and rabbits.
Being as clean as badgers, they can travel through badger burrows without causing much fuss and being capable of opening shellfish they are able to provide foxes with treats. In turn, foxes will protect them from larger predators and bring them harder to fetch food scraps.
Nifflers can usually find a way of getting on with most creatures, being rather placid and peaceful animals themselves. They are playful as otters and are deeply family oriented. When a niffler dies it pulled from the sett and buried outdoors. The area is then guarded until the carcass is too putrid for carrion eaters, before a trinket is hidden nearby that nifflers from the family will polish regularly. This indicates to non-related nifflers that this trinket is a marker, and may result in polishing from strangers as well. This is how they are remembered through generations.
Nifflers groom one another with their bills and claws, paying particular attention to the back and the neck, which is always hardest for one to reach. They can also be inspired to do this for others who share the sett, as knotted and gnarled fur is never fun and they are always happy to lend a paw in these situations. It is a sign of affection and friendship for a niffler to groom someone, but can at times just be a sign that one is lamentably dirty.
While very placid and friendly creatures, nifflers have all the ferocity of badgers when their home is threatened. They give warnings with growls and snaps, as well as by kicking dirt with their hind paws. If this doesn’t work they puff out their fur to look much bigger and make loud barking noises. If this fails, they will attack – their bills will snap, latching on to necks or chests and they will hold on in order to kick with their back claws as hard and frequently as possible while gripping like little pitbulls. They usually attack in groups, but a lone niffler will do the same if they or their sett is threatened. Nifflers are vicious when family is at stake and will have no care to themselves if it means family can get to safety. This is often how poachers catch them, as one simply needs protective gear and can walk off with the attackers to have them sedated while the others flee.
If taken from the sett:
Nifflers are typically very troublesome as they fight to get home again. Typically the fastest method of calming them is a forgetfulness potion; by forcing them to forget where home is, they become immediately dependent on their handler as this is now their only home. They can become extremely distressed by change afterward, and very easily lost. They lose some of their ability to trust their own senses and are always aware that this is Not Home, but with no ability to Find Home, they must simply build a new one.
It is for this reason nifflers are notably affectionate toward human owners after being captured and sold illegally. The niffler has accustomed themselves to the fact that this is their home now, and as such adopts the human into their sett-function. However, they can be prone to despondency and fits of bad behavior.
The former will result in one’s niffler simply laying about and not moving, hanging limply in the hand, refusing to eat and even turning away from shiny things. This depression can be alleviated either by releasing the niffler into a sett, where they will be quickly adopted by their fellows and may even find their way back to their proper sett with their help, or by bringing a pet into the home. Nifflers are particularly fond of cats, dogs and literally every other magical creature. They do not like owls.
The latter is a direct result of how determined to get home your niffler is. They will do everything in their power to encourage you to set them free. The best way to tame this (aside from more doses of forgetfulness potion!) is to hold your niffler frequently. Frequent holding and pets and patience will lead to something like domesticity, as the niffler will come to learn that you need them – and though you aren’t the home they want, they will make the home you need, because they’re at their core very helpful creatures.
What This Means For Trouble:
Trouble is – in the plainest of terms – a rescue animal. Newt is hardly likely to take a social creature from it’s burrow – but obtaining one from a known seller or through some other means is highly likely. Trouble never settled in with his first human – he was taken from his sett and immediately focused himself on getting back, refusing to accept that he would be lost. All he needed was another niffler and he would be fine.
Trouble’s tenaciousness wasn’t good for him, He was impossible to domesticate and was very fight-ready, as he was a young boar taken from his sett just after pups were born. This attitude problem lead to all manner of stress for the poor fellow before Newt got hold of him, and he developed an extreme distrust and distaste for humans throughout the ordeal that Newt has managed to somewhat alleviate.
Because he is completely surrounded by magical creatures, Trouble’s worst behaviours did fade rather quickly as he settled into a feeling of home. Newt’s case became his sett – but now and then it hits him that there are no nifflers here, which means this is not home, which means he needs to find home. Whenever this hits, off on an adventure he goes – and he might make it if he wasn’t constantly distracted by shiny things.
Once distracted by shiny things, he’s off on a whole other mission, completely forgetting that he wanted to find home, because his tiny niffler brain knows he has a safe and good home with Newt in the case. So it becomes a nonissue (though it is very much proof of how bad forgetfulness potions are on nifflers) and he is eventually found by Newt and is more than happy to go home, convinced he’d just gone on a polishing mission until the need to find his family hits again, and well.
Off he goes.
Thankfully, there is always an abundance of shiny things to distract him, and he has built a very safe and happy home and nest with Newt. Instinct is very hard to fight, and he knows he has another place he belongs – but ultimately, if he ever did make it back to a niffler sett, he would miss Newt and his family in the case rather desperately, as they are very much his sett now.
