Lost in Stinkeye Swamp is the 24th book in the Give Yourself Goosebumps series.
Plot[]
You move to a new house called Swamp House. It is ugly, run-down, and reported to be haunted, but there is treasure hidden on the grounds. You have also been told that "Annabelle" has cursed the swamp. While exploring the basement with your new friend Zeke, you find a telescope and a two-hundred-year-old diary. Whether you take the telescope or look in the diary determines what happens in the story.
Story A[]
You read the diary, which belonged to "Annabelle." You realize that she must have something to do with the curse. The diary says that the house has a secret tunnel created by smugglers. You surmise that the smugglers were looking for the treasure, and the tunnel will lead you there. You find the tunnel, and decide to explore, but hidden dangers lurk along the way.
Story B[]
You take the telescope. It turns out to be magical and show you things you could not see before. You go out into the swamp, where a mysterious man tells you about the Annabelle, a boat whose crew were all drowned. There is treasure on board the wreckage, and you decide to use the telescope to help you find it, ignoring the man's warnings...
Side story C[]
From story B, instead of the mysterious man, you meet up with a guy who claims to be a park ranger. He's not, and clues from him lead you to a witch named Annabelle who lives in the swamp.
