This story took place last month.
You usually get your period after you turn 11 (that's when I got mine), but Star got his much earlier than that. One day, the Freedom Crusaders were looking for someone to help, when they found Star moaning and groaning on the moon chair while wearing underpants with pads inside. Nina told them that he had gotten his period and had cramps, when there was pain throughout his body. The three girls thought it was weird that a 4-year-old like him would go through puberty, though Nina explained that it just came randomly. They tried to search for something to help him down and get rid of his cramps - Bean handed them some water, Easton gave them some of his sensory toys, and Kelly and Chica tried giving him a massage, but none of those worked. Just then, Banjo remembered that the civics center had a spa, so they went there and put Star in a massage bed where they played some calming classical music (the same one they had Easton listen to when he kept having nightmares (see https://www.artstation.com/artwork/K3Jmoo)), which quiet him down and stopped his cramps to the point he didn't want his underpants and pads anymore. And so the day is saved thanks to Noodle, Patty, and Banjo!
