Sandy stands outside the Krusty Krab, holding a sign that bears a striking resemblance to a Krabby Patty...if you tilt your head to the side and squints your eyes. Her rump is painted in the colors and shape of the iconic burger, and she's twerking and clapping it to attract customers.
As she continues her display, she lets out a frustrated groan, the constant clapping getting to her.
"Ugh...my cheeks are sore."
