Weekend at Poison Lake is the 8th and final Special Edition book in the Give Yourself Goosebumps series.
Plot[]
This book has four almost fully distinct main storylines. Rather than providing the reader with a choice in order to determine which storyline is followed, this book requires the reader to pick a lucky number. The lucky number is then employed at several points throughout the book, making the course of the story more random than voluntary. Which storyline you follow depends on the lucky number you choose (and thus, the page you first go to):
Story A[]
Your lucky number is 2. Your friend Nathan's parents are staying at Poison Lake, so Nathan invites you and your other friend Tamika to come along.The first thing you do is swim in the lake, but a neighbor warns you that swimming is not allowed because the lake really is poison. But being in the water makes you smell disgusting, and you can't shower off the stench. This storyline is based around you trying to get rid of the smell while surviving a bunch of creatures (insects, wolves, etc.) that are suddenly drawn to you because of it.
Story B[]
Your lucky number is 3. You go on a family vacation to Poison Lake. Your parents have heard the lake is dangerous, so they ban you from the water. But your bratty little brother dares you to swim in the lake, and you do it. Your skin turns green and luminous, and then a spaceship appears in the sky above you. You have been poisoned by the water and need to get an antidote from the aliens, but they will give it to you only if you can get an ice cream company's secret recipe.
Story C[]
Your lucky number is 4. You're staying at Poison Lake with your family, who have been warned that the lake is poisonous. An old lady tells you that this isn't true. Jewels were hidden in the water after a robbery, and a couple who had witnessed the robbery (the Bittermans) made up the story about the lake being poison, so they could get the jewels for themselves. You decide to search the lake for jewels, but you're in danger from both the Bittermans and the horrors that await you in the lake.
Story D[]
Your lucky number is 5. While walking your dog Harley at Poison Lake, an old man encourages you to swim in the water. You decline because everyone knows the lake really is poison. The man then turns into a moss-covered monster and tries to force you into the lake. You and Harley must now escape from the "Moss Man" who wants you to swim in the water.
