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.

It's Crafty Camper Career Week, and Carly is so excited. All campers are paired with a professional in their respective field, and Carly's assignment is to shadow a train engineer. After her grandfather organizes a visit to Steamtown Pennsylvania, Carly becomes inspired to improve trains in the future.
