The Doom of Planet D
Tales from the Wonder Zone: Stardust
When the inhabitants of the fourth planet from star 11041536-G fled, they left behind a Danger beacon warning all who discovered their planet to stay away. Thousands of years later when the Earth survey ship Magellan arrived, they couldn't understand the danger. Nothing about Planet D seemed remotely dangerous. In fact its only inhabitants where cuddly, cartoon cute creatures. Oh, oh.
