One of my biggest thrills was to see The Cow That Went Oink published in a Spanish language edition. I enjoyed seeing how the different animal sounds were translated from English to Spanish.
For example, "moo" becomes "muu." "Hee-haw" becomes "ji jaaa." "Baaa" becomes "beee." "Cock-a-doodle-doo" becomes "kikirikiii."
Interestingly, the only animal sound that is the same in both English and Spanish is "oink." I found that amusing!
