They did this one already! So here, when an intense magic stops Yue and Keroberos returning to their borrowed forms, Sakura tries to hide them at home but finds the task a challenge. She forces Keroberos and Yue to help out with the chores and learns that the Bubble was designed for giving Keroberos bubble baths, eventually finding a way to block out the powerful magic to allow her guardians to transform back into their borrowed forms. Overall, I rate this episode a 100%!
