A scientist on an island was experimenting to make spiders twice their normal size, but something went wrong and caused all the spiders to rapidly grow larger. The next morning, a man named Wei discovered the lab covered in webs and the scientist trapped upside down in a cocoon. Wei cut the scientist free and ventured into the jungle, where he encountered and fought many oversized spiders, including the king spider. Wei was able to defeat the king spider by striking its jewel, causing all the spiders to shrink back to normal size.
