Soap is a white round soap bottle with a face inside a square pink label with pink horizontal stripes above and below. On her head is a pink cap with a pink pump. Her arms are on the sides and her legs are at the bottom of the bottle. Soap excels in maintaining order. At the start of the series, Soap is often seen fretting over germs, and can usually be seen cleaning things with the small blue cloth she carries around with her to scrub and wipe things, even if they are already somewhat clean.
