Bugs is reading The Song of Hiawatha out loud to himself and the saga turns real as a pint-sized, Elmer Fudd-like Hiawatha (minus the speech impediment) turns up, paddling his canoe.
As with Elmer, Bugs spends the rest of the cartoon tormenting his would-be devourer, who finally breaks his arrows in anger and disgust, and paddles his canoe away while Bugsy finishes his reading of the poem.
