"When Friends Get Mad" is the first segment of episode 19 in the fourth and final season of Little Bill. It originally aired on February 6, 2004 on Nick Jr. In this episode, Kiku accidentally ruins Little Bill's painting with water. He gets mad and crumples up Kiku's painting, causing her to cry.
The episode starts with Little Bill and his friends painting pictures of Things We Like About Spring to decorate the room's bulletin board. Little Bill is very proud of his painting of a spring day, with flowers and trees in a park, but when Kiku tries to look closer, she accidentally knocks over the water used to rinse the brushes that spills on Little Bill's paper, ruining it. Close to tears over his wrecked hard work, Little Bill gasps, "Look what you did!" Kiku tries to apologize, but he just gets madder, and responds by crumpling up her paper. Kiku begins to cry too and says, "Little Bill, I said I was sorry!" Fuschia calls out for Miss Murray. Miss Murray shows what happened to Kiku's painting. Kiku says, "I didn't mean to do it!" Miss Murray tells her comfortingly that she knows she didn't. Little Bill doesn't understand why everyone "sides with her," and expects him to apologize! He won't feel sorry at all because Kiku started it. Andrew said that was mean. Then Fuschia says, "If you don't say you're sorry, I'm not gonna be your friend!" Miss Murray told Little Bill, Fuschia and Andrew to calm down and puts Little Bill in time-out as a punishment, explaining that while she knows he is angry, he shouldn't have messed up Kiku's painting (even though she messed up his, which is not the same thing). When she explains the difference between how they wrecked each other's paintings, he thinks everyone is on Kiku's side. Miss Murray says that they are not taking sides, but what he did was wrong and didn't solve his problem, and that he should apologize to her. He refuses and just wants to go home, which she tells him everyone will be going home soon. Miss Murray leaves him in the time-out chair while she cleans up the rest of the paint, but he doesn't care because he still isn't sorry.
Later, when he gets home, Alice the Great has learned about his hard day (but not how it happened), and Little Bill tells her and Bobby about it (as she gives the boys a bowl of grapes to share), and Alice says that while she'd also be pretty upset if anything she liked very much got messed up, she is certain that Kiku didn't mean to wreck Little Bill's painting. Bobby offers to tell him a joke, but it doesn't make him laugh; however, he tells him to ask him if he needs another joke.
That night, he states to his parents that he doesn't want to go back to school. After guesses from Big Bill, all of which are answered, "no," he explains (when Brenda asks him what's wrong) what happened, and they talk to each other, his father asks him if it was right to crumple up Kiku's picture to solve his problem and he says no, prompting him to admit that what Kiku did was an accident, but what he did was on purpose because he was mad, making him understand that crumpling up her painting was the wrong way to treat her.
The next day at school, Little Bill apologizes to Kiku for what he did, offers to help make a new painting with her, and ends with Little Bill and Kiku restoring their friendship magic... then Little Bill tries out the joke Bobby told him, but Kiku assumes the answer is, "You tell your mommy?" But they both laugh anyway.
*This is the second time Kiku cries. The first was in Buds.
*In this episode, Little Bill is mad and crumbles up her painting, and now he must make it up to her. At home, he is still not sorry and at home, Alice the Great and Bobby tell about Little Bill's day. Alice the Great says, "Your brother had a hard day at school today." Little Bill talks about his day with Brenda and Big Bill. This is the second episode where someone is mad (In "[[The Wrong Thing to Do]]," April gets mad at Little Bill for drawing on her door, and then Brenda sends him to his room. In the end, Little Bill additionally says sorry to Kiku and begin to become friends.
