Are the Latin sentences pretty creepy?!
I've only done French and Latin on Duolingo, but so far the French sentences have been what you'd expect ("it's raining"; "I wake up early"), while the Latin sentences were often weird and slightly sinister: "I collect dolls and bones," "the young man wanted to get down from the altar." And then there are all the poop-filled toilets and the drunk parrots smashing up the forum. Silly but fun. It makes learning Latin more light-hearted and less dusty and dour than it's usually given credit for.
And you have absolutely no idea what the evil goddess Minerva will do when the next advanced release of the Latin course appears. The rumour is that it will make The Texas Chainsaw Massacre look like a pleasant stroll to the forum...
But I never believe rumours. Do you?
I'll forever remember the Spannish "The bear drinks beer" and everyone in the comments like "whoaaa... This one bear is so cool !" What's fun about those, it's that they sometimes are strange, and sometimes really simple sentences become so fun just because of the comments (like "Where do I come from ?" (Latin course) --> Duolingo diving into philosophy ? xD)
I just loved the "Nature" part, you would imagine it's focused on nice stuff like "sun is shining brightly, grass is growing nicely, etc", but boom! You get all those fires, water running under the floor, destroyed buildings and bridges, oh, and the word for "violently", of course!
