Freshies is a brand of baby wipes that appeared in Diary of a Wimpy Kid: Old School. Greg brings them to Hardscrabble Farms and puts them at the bottom of his bag to hide them from his Mom, who reserves them for Manny. Greg plans to buy as many Freshies as he wants when he's rich.
At Hardscrabble Farms, Greg is afraid that the chaperones will confiscate his Freshies. He uses them to clean himself on the second day. After his cabin is raided, Greg notices that all his baby wipes have been used up.
