In the forest, there is an aerial city inhabited by a tribe of pygmy Indians, the ghostly Batmen. Their leader is the great Marcus, a former acrobat with exceptional hypnotic abilities and able to fly thanks to special canvas wings. Now because of him, fear reigns in the forest!
After they finished the adventure with Marcus and his batmen, Zagor and Chico go up a watercourse in a canoe, when a gigantic river boat, the "Star of the River", appears in front of them. Mister Sparrow who owns it, uses it as a floating gambling den. Sparrow robs passengers using a rigged roulette wheel. This is what Zagor and Chico will discover when they get on board. And Chico will have to face the fearsome Arturo, the kangaroo-boxer in a boxing match!
Note: Gallieno Ferri takes up the idea of an episode of his series Kid Colorado, which also takes place on a riverboat equipped with rigged games room (published in BIG-HORN N. 4 and 5). There we also find a fight against a kangaroo.
Another short humorous tale that appeared as an appendix to Zagor. The protagonist is a certain Teddy Noccol who, upon reaching Okay-baby City, is inexplicably elected sheriff but… there is a plot afoot!
