Bumblebee's First Life on Earth

In the night sky above Earth, B-127 plummets to the ground after a vicious battle with Blitzwing. Landing in a junkyard with his memory cells damaged, B-127 quickly scans a nearby Volkswagen Beetle, taking on its form to hide from a pair of approaching humans. A few days later, while returning from buying food for her dog Conan, Charlie Watson spots the abandoned Beetle. Investigating further, the vehicle shocks Charlie when it displays sentience, and she agrees to let it come home with her. At Charlie's home, the Beetle transforms into B-127, shocking her and Conan. The small dog frightens B-127, but Charlie restrains Conan, introducing the two of them and deciding to call the robot "Bumblebee". Bumblebee attempts to pet Conan, only for the dog to jump up and bite his hand, shocking him and Charlie.

Bumblebee at first practices his transforming by imitating a statue, prompting Charlie to remind him that he can just turn into a car. Bumblebee assumes his Beetle form through stylish transformation sequences, attempting to impress Charlie, but only succeeds in hurting her and Conan due to being too close, then destroying a park bench and trash can in his second attempt. The impact jostles part of Bumblebee's frame off, and a holographic projector displays a message from another robot, with Charlie asking who it is.

At the Watson house, Charlie Watson attempts to familiarize Bumblebee with more Earth customs by demonstrating how to cook. She tastes the soup, but decides it needs more salt. As she steps out to buy some more, she asks Bumblebee to keep mixing the fried rice and soup for her, but warns him to be careful and not overdo it. Bumblebee agrees, fantasizing of mixing the rice perfectly and earning Charlie's praise.
