Deep Water, Dark Water is the twenty-second episode of Slugterra.
Blakk has hired Brutale—a thug as brutal as his name—to build a Deep Water Rig to drill for Dark Water at the bottom of the Cavern Sea. Needing some water-breathing labor for the job, Brutale steals Marvolio Drake's reptilian pirate crew. Desperate to get his men back, Drake forms an unlikely alliance with the Shane Gang, who are just as desperate to shut the Dark Water rig down.
