Go! Anpanman: Roboly and the Warming Present

"Comet Robo is a planet inhabited by robots capable of crafting anything. Roboly, a robot girl who lives there, excels at everything she does-until she discovers there’s one "important thing" even she can’t create. Determined to find it, she leaves Comet Robo with her small robot bird companion, Koto. Along the way, they find a gift box containing a beautiful music box and follow its trail to Anpanman’s world, hoping to return it to its owner. As Roboly spends time with Anpanman, she feels an unfamiliar warmth in her chest. Puzzled by these new emotions, she slowly grows closer to Anpanman and his friends. Meanwhile, Baikinman builds a powerful mecha called "Roboking" and wreaks havoc on Comet Robo. Can Anpanman and his friends stop Baikinman and protect the planet? And will Roboly finally uncover the "important thing" she’s been searching for?"
