X-Pod was a subtheme originally released under the Designer theme from 2004 to 2005, and then later under the Creator theme in 2006. X-Pods are small, round containers which can be used to build on, or store LEGO bricks. They were designed for portability, because, as the subtheme's tagline went: "The urge to build can strike anywhere: Now you'll be prepared!".
