Freddy and the Baseball Team from Mars — Walter R. Brooks

In Freddy the Pilot, Freddy takes to the air to save Mr. Boorschmidt's Stupendous and Unexcelled Circus from the evil schemes of Watson P. Condiment, the comic-book tycoon. Soaring through the clouds may be scary for some, but for Freddy it's all in a day's work as he takes on Condiment's flying henchmen, a feud between the skunks and the rabbits, and even the U.S. Army!
