Dirty Dozen

As you're preparing to leave for Oregon, you meet a rambling traveler. Find the missing number and type to figure out what you need.

Come and hear the story of my august accomplishments. Did you ever see a three-headed dog? Or how about a dragon? Yesterday I captured a bull just like the one that lived in a labyrinth. I had to do all of this with zero help - a goose egg! On top of that, it was a long march back home. And I had to trek through all the mud - you know what they say about April showers. I tried asking the pipers I met on the way back for directions. But I couldn't hear them because a rooster was crowing at the same time. Despite all these setbacks, I must press on to my next mission of retrieving a belt from the Amazon. The bird on that pear tree gives me hope.
