Swee'Pea (alternatively spelled Swee'pea and Sweapea on some titles and once called Sweep Pea) is a character in E.C. Segar's comic strip Thimble Theatre/ Popeye and in the cartoon series derived from it. His name refers to the flower known as the sweet pea. Before his addition to the animated shorts, the name "Sweet Pea" was a term of affection used by main character Popeye. In the cartoon We Aim to Please, he addressed girlfriend Olive Oyl that way.
In the comics, Swee'Pea is a baby found on Popeye's doorstep (actually delivered to him in a box) in a July 24, 1933 strip. Popeye adopts and raises him as his son, or, as he puts it "boy-kid". Initially, Swee'Pea's speech consisted entirely of the sound "glop". As the years went on, Swee'Pea apparently aged enough to speak normally, and could throw punches if necessary; however, his appearance remained that of a crawling baby. In the strip for August 17, 1933, Popeye christens Swee'Pea as 'Scooner Seawell Georgia Washenting Christiffer Columbia Daniel Boom'. Although Swee'Pea remains his most common sobriquet, he is occasionally referred to as Scooner by Popeye and others in later strips.
In November 2004, Popeye officially adopted Swee'pea in a ceremony officiated by Judge Greg Mathis and hosted by the National Council for Adoption in New York City.
