Doggy Dog (du) urgently has to visit the bathroom so he storms into the encampment's bathroom ((e)n4) to pee on the banana tree (⺁), but the eye of providence (目) is determined to protect the tree standing guard armed with a cross (十) and protected by a shield (盾). The eye of providence is so determined to stop Doggy Dog because it'll have to clean the bathroom later.
