Nobody's expecting much from a movie tie-in short. This one is a magic lesson that actually understands what makes precure work: the transformation, the teamwork, the moment before everything changes. It moves fast enough that you don't notice it's basically a commercial, and by the time Mofurun does something genuinely cute, you're already bought in. Kids get a straight hit of magical girl energy. Adults recognize the craft underneath.
Cure Miracle and Mofurun hold a magic lesson aimed at the audience, but the two soon get sidetracked and start goofing off. When their play gets out of hand, Mofurun ends up needing rescue, and Cure Miracle has to turn to the audience for help to save her friend. The special is a short 3DCG piece in the magical girl genre, shown in theaters together with the Mahoutsukai Precure! film Kiseki no Henshin! Cure Mofurun!
