Cat Dog Car Doll

Cat Dog Car Doll is an animated series based on a Chinese animated kid's song, 玩具进行曲.

Plot
Cat Dog Car Doll focuses on the titular quartet, a group of anthropomorphic toys that are best friends and roommates: Cat, the cute one who is excitable and happy; Dog, the responsible one who tries to keep the group from causing chaos; Car, the reckless one who loves to go fast and break speed limits; and Doll, the motherly one who can be overbearing at times. The toys are owned by an unnamed person, who often has to leave the house for various reasons, prompting the toys to come to life and get into shenanigans. The show is set in China, where a lot of locations end up being the setting for many episodes. The four characters live in a house, which sits in the middle of China.

Main

 * Cat - a cute white cat with red hair and wears red overalls. She is excitable and happy a lot of the time, although she can get serious whenever she needs to. She has a crush on Dog, and is rarely ever seen frowning.
 * Dog - a white dog with light yellow hair and a blue-white striped T-shirt. He is the most responsible out of the entire group and tries to keep them from causing chaos wherever they go. However, he also has several plans, just in case they do end up causing chaos.
 * Car - a yellow car with green accents. His lights are his eyes, and his grill is the mouth. He is very reckless and loves to go fast, even if he ends up breaking the speed limits. That being said, he does care about the others and will take them to wherever they want to go.
 * Doll - a doll with orange hair, a red-pink hat, a green-white dress, and yellow shoes. She is very motherly to the others and cares for them a lot, but she can be overbearing at times.
