Goosebumps HorrorLand #2 Creep from the deep

It's a whole new ride from master of horror and bestselling author R.L. Stine -- with a story so fiendish that it can't be contained to just one book! Billy and his sister, Sheena, unwittingly dive into a terrifying mystery when they accept a surprise invitation to HorrorLand -- the amusement park that always lives up to its name. But first Billy and Sheena must sink or swim aboard a doomed ship that happens to be underwater -- with a captain who happens to be dead. At least, he used to be!
