"Oh my god!", said Christina. "The Chronivac really works! I wanna change something else." She sat down at her computer, when a box appeared on screen.
"Do you know about Modules? Modules are downloadable add-ons that can enhance your Chronivac experience. As it is now, the Chronivac can only do simple changes. Modules are fine-tuned to do specific things. Try looking at our database of modules!"
Christina clicked the link it gave. Another box popped up, this one containing a large list of the modules. She scrolled the list, looking for a fun one.
