"I have hats!"
Translation:Ich habe Hüte!
You could definitely say that but I would not be a translation for "I have hats". "der Hüter" with the letter R is a guardian. Great opportunity to learn about the popular German lullaby: http://de.wikipedia.org/wiki/Schlaf,_Kindlein,_schlaf Here, the father is a "Hüter".
