it's missing grammar. even with HEAVY interpolation and deduction i'm guessing you're trying to say something like "I seek language knowledge (i want to learn) in this weird bad language, but it's not (or did you mistake this word for ale and wanted to say all?) like animal speech." but that might be a lot of conjecture on my part
first of all you've messed up the order of words in phrases. in toki pona, the head of the phrase comes first, so it's a "balloon red big" not a "big red balloon" (sike loje suli).
Second of all, you did use the word "li" there which is good, but you're missing another very important word for SVO sentences, the particle "e". That word makes it so that the phrase following it is the subject of the sentence, so "mi lukin e ona" means "i see them"
Thirdly, the word "lon" is kind of confusing me, which is probably because your sentence construction is not very good. but if the start of the sentence is trying to say something like "I'm learning this weird language" or "i want to learn it", i would not use lon, i'd either say "mi kama sona e..." or "mi wile (kama) sona e..."
fourthly, animal sounds have a special word in toki pona, that being mu. yes it sounds like moo.
so the whole sentence would be something like "mi wile kama sona e toki nasa ni. taso, ni ale li sama e mu."
