This calls for an experiment. Can you squeeze out all of yukkuri's shit ? Will the shit stopped, thus proving there's difference between yukkuri's "normal" paste and shit ? If so, will there be paste left inside and how much ?
Methodology of the experiment need to ensure that normal paste won't just be squeezed out too. For example, using pump that only suck out yukkuri's shit painfully, while keeping them alive and lucid throughout the experience. Oh, and the device is nature-friendly made from biodegradable material and part of the sales profit goes to charity.
Let's get a-ll of it out right now
Ugh...So filthy...
