Ahh hungarian does the same tho arguably it has more forms. As far as i know finnish has 5 kinds of possesive forms, two numbers and 15 cases indicated on a noun while hungarian(generally cause there are a few more or less depending on noun and what you count) has 6 possesive forms, two numbers and 19 cases(so normally you would count 19 but one of those doesnt apply to general nouns like “dog” so its 18 but then theres one that doesnt count as a case but functions exactly like one so id say still 19 in this case and that hungarian actually has 20 cases) and two bonus possesive forms. If you multiply everything up you get 180 forms for finnish and 266-400ish(but the bonus possesive forms can form infinite loops so actually technically its infinite) for hungarian. Heres a simplified explanation of this:

-Two basic numbers are “kutya” for dog and “kutyák” for dogs

-19 cases(or “case-like” suffixes):

Nominative: kutya(not marked, the actor in a sentence so “the dog chases the cat”)

Accusative: kutyát(the one being chased in the previous example)

Dative: kutyának(kinda like “to”, “i gave it to the dog”, but also indicates a genative so some people count it seperately but its the same form so it doesnt really matter)

Instrumental-comitative: kutyával(english “with”)

Causal-final: kutyáért(“for” the dog)

Translative-factive: kutyává(“into” in the sense of “turn into a dog”)

Inessive: kutyában(“in”)

Illative: kutyába(into)

Elative: kutyából(“from” but like “out from the inside”, also used if something is made out of a specific material, or if you say something like “there are too many dogs here”)

Superessive: kutyán(“on”)

Sublative: kutyára(“onto”)

Delative: kutyáról(“from on top of”)

Adessive: kutyánál(“at”, also used to mark possesion “the toy is at the dog”)

Allative: kutyához(“to” but more like the side of thing usually, not directly to the dog but close to the dog)

Ablative: kutyától(“from”)

Terminative: kutyáig(“until”, a destination)

Essive-formal: kutyaként(“as”, literally, if dracula turns into a bat and bites someone youd say “as a bat” with “denevérként”)

Essive-modal: kutyául(“as”, more like the manner, dracula bit someone like he was a dog but wasnt actually a dog “kutyául”)

-And then my bonus, sociative: kutyástul(i guess “both”, if someone kidnaps you and also takes the dog cause like you were walking the dog or some shit, you say “both the dog and me were kidnapped” “kutyástul elraboltak”)

Then you have the possesive forms which are basically just “mine”, “yours”(singular), “his/her/its/their”, “ours”, “yalls” and “their”.

You also have the bonus forms which are like asking the question “Who’s bone is this?” and you answer “the dog’s” which in hungarian is marked with “-é” so “kutyáé” and then also another one which is better illustrated with a name like “Péter”(Peter) so if you say “we ate dinner with the company of Peter” that would be “Péterékkel” but just the possesive thingy is “-ék” so peter and his company is “Péterék”.

Uhh yeah. Also the infinite loop means “kutyáéiéiéinek” is grammatically correct tho nobody would say this. But ive heard a few layers deep in actual conversations so thats a thing.

Explain what’s going on with their language
