Hosts Carly and Charlie are nominated for a Daytime Crafty Award! The awards ceremony is just around the corner, and Casey is helping them with their costumes…until she comes down with a cold! To avoid getting sick from the germs Casey is spreading throughout HQ, Carly and Charlie must understand all there is to know about germs. They head to Germfree Laboratories and Mushroom Mountain to examine good hygiene and health practices.
