We discuss a trajectory of penguins' faeces after the powerful shooting dueto their strong rectal pressure. Practically, it is important to see how farfaeceses reach when penguins expel them from higher places. Such information isuseful for keepers to avoid the direct hitting of faeceses. We estimate theupper bound for the maximum flight distance by solving the Newton's equation ofmotion. Our results indicate that the safety zone should be 1.34 meters awayfrom a penguin trying to poop in typical environments. In the presence of theviscous resistance, the grounding time and the flying distance of faeces can beexpressed in terms of Lambert {\it W} function. Furthermore, we address thepenguin's rectal pressure within the hydrodynamical approximation combiningBernoulli's theorem and Hagen-Poiseuille equation for viscosity corrections. Wefound that the calculated rectal pressure is larger than the estimation in theprevious work.
