Bosko the Doughboy

[4] The cartoon opens with images of explosions, gunfire, and heavy artillery; one character even fires into the camera.

Bosko shows a rare moment of anger but is quickly cheered up by a fellow soldier.

Bosko finally decides to fight back and downs an enemy bomber (actually a pelican) by using a fellow soldier as a cannon.

A friendly hippopotamus is shot down by heavy artillery, which Bosko destroys with a pair of Longjohns-turned-catapult.

Bosko is usually infallibly happy and chipper; Doughboy forces him to drop this demeanor and fight back.
