The Giant Praying Mantis is the quinary antagonist of the 2015 film adaptation Goosebumps, based on the book series of the same name. It is one of the monsters to be released from one of R.L. Stine's manuscripts by Slappy, and wreak havoc on the town.
It encounters R.L. Stine, Zach Cooper, Hannah Stine, and Champ. It chases the car that they are in and destroys half the town doing it. It manages to follow them to a grocery store, but they already escaped, so it destroys the car. The Giant Mantis shows up at the school and attacks a student close to the window.
The mantis, along with all the other monsters, chase the gang to the abandoned amusement park. It knocks the Ferris wheel off, with Zach, Hannah, and Champ inside, but they survive. Zach managed to finish the book just as the monsters reached them, and promptly opened it, causing a vortex to suck the mantis and all the monsters in the book.
