Which animal would never hit the walruses if walpole was there?

The phrase seems to be a playful riddle rather than a straightforward question. If we interpret it, one possible answer could be "a gentle animal," such as a rabbit, as it would likely avoid conflict and harm towards the walruses in a peaceful setting. The mention of "Walpole" might suggest a historical or literary reference, but without further context, the emphasis remains on the idea of peaceable coexistence.
