Kaiketsu Zorori: ZZ no Himitsu

A film marking the 30th anniversary of a children's book series features Zorori building an alarm clock machine to ensure he wakes up in time for free donuts. When Zorori recalls his mother and cries, strange events occur—flashes of scenes appear, and the ZZ mark on his costume vanishes. He values this mark deeply, as it was sewn by his mother, though its significance is unknown to him. After a crash landing in a city street, Zorori, along with Ishishi and Noshishi, is rescued by a fashion student identified as Zororene, his mother. The machine is revealed to be a time machine that transported them to the past. Zororene and later Zorondo Ron, Zorori's father, assist the group in retrieving their time machine from the police and a kaijuu.
