You obviously refused, cause R U B B E R D U C K Y, so King Crab was not too happy, cause he wants a rubber duck to swim with too. So he took the ducky and tried to kill you. But luckily, you escaped by hiding in an old submarine. You got it to work to save your ducky. Can you save your ducky before time runs out? Your submarine is very weak, so it requires your HP to run its flashlight...
