I second hedgehogs for Germany, they’re so cute! Also, or squirrels are so different from the US kind, they’re just unfortunately a lot shyer, too

I second Duolingo and Drops for mostly vocabulary learning, and then I’d supplement with a textbook for grammar and a more structured learning experience. I keep seeing the everything learning german book recommended, but really, just choose whatever looks reasonable and go through it doing all the exercises

What eras do they have/use?
