The Popsicle Twins are two striped popsicles consisting of red, white, purple, and blue colors. They have a pointed tip on the top.
Plankton enters SpongeBob's mind to find the Krabby Patty Secret Formula. He enters a world of happiness and candy. Almost everything is sentient. He sees a Waffle Boy chasing a Syrup Girl. He then runs past an Ice Cream Boy having a "fudge fight" with an Ice Cream Girl. He sees two Cupcake Girls playing patty cake. He complains about the sweetness of the environment. He then hears the Popsicle Twins greeting him. He turns around to see them. They ask him to play with them and Plankton gets scared. They say "Hurry" and then "Before we melt." He then becomes even more scared. The Popsicle Twins start laughing as they melt which causes Plankton to run away from them.
They were voiced by Kate Micucci and Riki Lindhome, from the comedy musical duo "Garfunkel and Oates."
They are based off of a Popsicle called "Red, White and Blue Turbo Rocket" or "Bomb Pop."
They are also a reference to the twins who hold hands saying "come play with us" in The Shining.
