Sakasete! Chibi-Robo! (Japan)

About

A company known as Citrusoft creates a new model of Chibi-Robo called the Blooming Chibi-Robo to help heal the declining health of the planet. This new model is distributed to parks everywhere for free to improve their quality and get more people to visit them and care about the environment. One Chibi-Robo is sent a park in desperate need of help after it has been forsaken by the people of the nearby town. Over the course of his mission, Chibi-Robo is aided by a manager robot named Chet and makes friends with many of the town's toys, who are eager to help him restore the park. He is also impeded by black creatures called Smoglings, their general Sergeant Smogglor, and their leader Miasmo, who are determined to spread pollution and stop the park's revitalization by any means necessary. As Chibi-Robo continues his mission, Sergeant Smogglor's backstory is revealed: he was once a toy called General Greenthumb who was originally owned by a child, but was abandoned at the park. Greenthumb came alive and, seeing the beauty of the park, he swore to protect it. Soon after, Miasmo attacks with a group of Smoglings. Later, Greenthumb managed to infiltrate Miasmo's factory base, determined to face him. Unfortunately, he is quickly overwhelmed and Miasmo uses his power to brainwash him, turning him into Sergeant Smogglor. After this final flashback, Greenthumb is freed from Miasmo's control. Miasmo appears to him, calling him a useless piece of trash, and abandons him. With his memories restored, he is upset by his actions and leaves. After enough flowers are planted, Miasmo transports Chibi-Robo to his dimension Exhaustia for the final fight. Greenthumb appears and sacrifices himself to help Chibi-Robo defeat Miasmo, although he claims that he can never truly be stopped as long as humans continue their current ways. Miasmo's defeat causes the Smoglings to turn pink, indicating that they are now friendly. Seeing the beauty restored to the park, Greenthumb is grateful for Chibi-Robo for his hard work. With a final farewell, he dies, giving Chibi-Robo an energy ball that grants him infinite battery power. Greenthumb's owner arrives and, convinced that Greenthumb is the one who restored the park, finally shows him some respect and takes him home.
