If you want to learn more about these beautiful instruments, visit Charlie Hind Ocarinas. There are many different styles. They’re works of art in themselves and you can play very satisfying music for self entertainment or the enjoyment of others. My dog, Mr. Ben, howls along with me when I play slow songs. He’s a real crooner 
As someone who has sort of an allergy to the giant sports culture in America, I want to personally thank you, Don, for drawing an instrument I’ve never heard of and educating me about it on this Super Bowl Sunday! Just wondering …. what does it sound like?
Howdy Karen!
The ocarina sounds very similar to a Recorder or wooden flute. There’s a link to the maker’s website under the sketch and he has some sound samples on his site. I’m like you, I suffer from the same allergy 
I’m happy to have enlightened your Super Bowl day
Good to hear from you
