Rerun

Even though he’s Lucy and Linus’s younger brother, Rerun is quite different from them both. He likes to spend time playing the sandbox, enjoys frolicking with Snoopy, and making underground comics. He’s often seen racing across town on the back of his mother’s bicycle. Rerun’s desire for a dog of his own is so great that he tries to adopt three of Snoopy’s brothers, Spike, Andy, and Olaf, but his parents won’t let him keep Andy and Olaf, and upon meeting Spike, Rerun isn’t quite sure that he is actually a dog.
