Plot[]

The gang's class biology teacher, Professor Elliot, has disappeared and the biology class is temporarily canceled until a substitute can be found. Since Professor Elliot is her favorite teacher, Velma is determined to find him no matter what and the gang agrees to help her. Velma asks Mr. Garrison what Professor Elliot was doing before he disappeared. Garrison replies that Professor Elliot took Violet's biology project about spiders to his house to mark it and he hasn't been seen since then. The conversation is interrupted because the school gets attacked by a monstrous spider. Scooby and Shaggy are terrified by the spider. The spider webs Garrison and several other teachers, and takes them away. Violet recognizes the spider as one of the spiders from her biology project. Velma suspects that the spider and Professor Elliot's disappearance have a connection. The gang gets Professor Elliot's address and they go to his house to uncover the mystery. The gang arrives at Professor Elliot's apartment to find it all webbed. They split up to search the building. Scooby and Shaggy find the kitchen and take some food until the spider appears in front of them. Scooby and Shaggy escape from the spider. Fred, Velma and Daphne find some web that goes to the basement. At the basement, they find Garrison and the teachers, cocooned in spider webs. Scooby and Shaggy show up chased by the spider. Velma faces the spider and angrily asks it what it had done to Professor Elliot. The spider spits web everywhere and the gang attempts to dodge every hit. But soon, Daphne gets webbed by the spider. Scooby, Shaggy, Fred and Velma then escape from the spider and split up. Fred and Velma come up with a plan: Since the regular spiders need to be on dry land and the water weakens them, so the spider creature can also have these weaknesses. Scooby and Shaggy run to a dead end and are cornered by the spider. Fred and Velma show up and use the water hose to spray water on the spider. The spider collapses and is revealed to be Professor Elliot. After freeing Daphne, Garrison and the teachers, Professor Elliot reveals to the gang how he became a spider: He tried to check how the spiders react with radioactive formula. One spider got a sample of the formula and bit the professor, turning him into a spider creature. Professor Elliot tells the gang, Garrison and his fellow teachers that because of this situation, he's resigning from the position as the biology teacher, much to Velma's dismay. The gang's class gets a new biology teacher, Mrs. Andrews.
