In "Miracles Do Happen", Avery Arable attacked Charlotte's 3 daughters--Joy, Aranea, and Nellie--resulting in Nellie getting stuck inside a garbage can and Avery destroying half of all the eggs and milk in the cargo while the Zuckermans and Arables are ready evacuate from Maine and find a new home in Alaska. In his attempt, Avery got bitten by an unseen force which later on turns out to be a male hobo spider named Fico. After making a full recovery and barely surviving Fico's toxic venom, Avery soon suffers an irrational fear of spiders, or arachnophobia.
In the Movies he also wanted a pig. In the cartoon version, he is seen entering carrying a jar of flies after his sister runs outside crying. Avery goes to the fair and has a good time. When he sees Wilbur crying, unknown to him that Charlotte died, he taunts Wilbur thinking that he's just having a good time. In the live action movie, he is seen carrying a slingshot when he walks into the kitchen and sees his sister bottlefeeding Wilbur. In the live action movie, Avery doesn't catch frogs or snakes but only tries to capture Charlotte the spider.
