When Cartman desperately asks for Butters' help to become a better sarcastaball player, Butters shows him a closet filled of jars of his "creamy goo", which are, in reality, the semen from his nocturnal emissions. Cartman ingests a jar of the "creamy goo", and believes that it made him feel better. This method soon becomes popular among other team players. As its popularity increases, a sports drink named Butters' Creamy Goo is commercialized.
At the end, Stan offers the drink to Randy Marsh, to help him realize sarcastaball could be played sincerely. After drinking it, Randy immediately finds out that the drink is actually semen. As a result, Butters is grounded for selling his semen to other people.
Stacks of the "creamy goo" can be found in Butters' closet. Individual bottles can also be picked up as junk items.
A bottle of the "creamy goo" is used as an artifact named "Flask of Orgasmic Power". It can be purchased from any food vendors.
- After Cartman first drinks Butters' Creamy Goo, he describes the taste as a "Grapey, bleachy flavor."
- During the commercials for "Creamy Goo", when the narrator says, "commitment", "compassion", and "comradery", he emphasizes the first syllable of each word, "cum", referencing the fact that it is semen.
