Marni has a promising future as a proctologist.
When in the tub with Stella, Marni will often get a little devilish. If she is sitting down and Stella is standing next to her, Marni will sometimes attempt to stick her finger up Stella's tushie. This will, in turn, tend to make Stella jump a mile!
Stella finally tired of this and, upon becoming the victim of another Marni tushie-attack, screamed out at her "Marni! Stick your finger up your own tushie!"
