Zippy tiptoed up to the bathroom door and stuck her hand into her ear and fumbled around (her ear was alien, large and hard to ignore, like her voice). She pulled out little by little a handle that extended from inside her ear. With one last tug it snapped with a popping noise. Zippy's ear waggled fromm the vibration of the suction. At the end of the handle was a three-foot long stick with a rubber plunging apparatus at least three feet in diameter.
"Super plunger!!!" Zippy proclaimed, naming the weapon to increase the awe of its power.

The following is quoted from Wikipedia's page on the "Anal Stage":
"The anal stage is the second stage in Sigmund Freud’s theory of psychosexual development, lasting from age 18 months to three years. According to Freud, the anus is the primary erogenous zone and pleasure is derived from controlling bladder and bowel movement. The major conflict issue during this stage is toilet training. A fixation at this stage can result in a personality that is too rigid or one that is too disordered."
Sounds like a character I know...
For everyone who isn't stuck in the anal stage, just try to imagine what it feels like. But not literally.
