Jacob Miller

Jacob Miller is the protagonist of the twenty-forth Goosebumps Series 2000 book, Earth Geeks Must Go!.

History
Jacob is supposed to be starting his first day of school in the 6th grade, but he quickly discovers something isn't right. He doesn't recognize a single person in his class and his teacher, Mr. Kray announces that he's actually in the "Trelth Grade". Jacob is even more confused as Mr. Kray begins writing Math equations in some undecipherable language he's never seen before. The keyboards his class uses to type papers also has this strange language and when Mr. Kray shows him a map of their location, Jacob doesn't recognize any of the countries or continents. When everyone is dismissed for lunch, Jacob is horrified to discover everyone is eating with their armpits and when he tries to eat with his mouth like normal, his whole class acts disgusted with him. He runs away to the woods and finds himself pursued by a mysterious girl, who introduces herself as Arlene. Arlene seems to be a human just like him, and can't remember anything about her past or how she got there. Jacob realizes he can't remember much of anything either.

In the woods, the two are nearly drowned in a pile of tiny bugs known as Splatters before their class rescues them, whistling to get the Splatters off them. Noticing a stray Splatter still clinging onto Arlene, Jacob places it back outside, where he encounters a rugged-looking man calling to him. Jacob isn't sure if he can trust the man so he ignores his pleas. He and Arlene continue searching for clues about what's going on, but find all the information is written in the same strange language. The two end up being chased after by the same man Jacob saw outside, and they decide to hide and look for clues inside a seemingly vacant house, which Arlene says feels somewhat familiar. Turning the TV on, Jacob sees a message from the planet's mayor-governor Dermar, who announces that the "Earth Geeks" have landed and must be caught and taken care of as soon as possible, Then, the man from earlier busts in and reveals that he is in fact their father and that Jacob and Arlene are siblings. He too has lost his memories but says they are all in danger as long as everyone is now looking for the Earth Geeks. He tells them to go to school as normal the next day, but things don't work out and Jacob and Arlene are ultimately exposed as the Earth Geeks when they fail to know the rules of a game common to the people of that planet.

Jacob's father attempts to escape the authorities in a car, but they all crash and wake up later in a prison. The Millers are brought to mayor-governor Dermar, who interrogates them about the location of a "weapon". None of the Millers know what's he talking about, but Dermar doesn't believe them and they end up being lowered into a cauldron of Splatters. Inside, Jacob hears the bugs telepathically tell him they aren't going to hurt him and to just cooperate with the mayor-governor. Jacob's father decides to play along too and says he does indeed have the weapon, giving enough time for the Millers to escape as the cauldron tips over, allowing the Splatters to attack Dermar and his guards, who run away in fear.

The Splatters reveal that they are the ones who erased Jacob and his family's memories and brought them here to Earth. Their leader, Grolff, placed a bomb inside Jacob's father's wrist-watch, intending to use it to destroy the planet as payback for being treated like bugs. Grolff orders them to hand over the explosive, but Jacob is able to hear his thoughts and realizes the Splatters intend to just kill them next. He snatches the watch from his father, and smashes it, setting off a loud noise that causes all the Splatters to explode. As they have defeated the enemy, the Millers are treated as heroes by the planet's people and given a lengthy celebration. However, they still want to return home. While only the Splatters had the space travel technology to do so, they are directed towards a man named Crazy Old Phil, who apparently has built a space-ship capable of taking them home. They visit Phil and luckily, his ship actually works and they seemingly land back home on Earth. Unfortunately, the planet is now overridden by lizard-like aliens who ask the Millers where they're from.
