The crew fends off the attacks from the Giant Marsh Worm... Will they get munched? Will they Kill it with Fire? Will they finally get some much needed rest?

A DM's Session Note: So for those that have asked... The crew shouldn't have had advantage to hit a huge or larger creature and no disadvantage while grappled (vs Restrained). However things happen during game play that get overlooked and sometimes its better to throw the players a bone and resolve it later! Happy Hunting and thanks for the input!
