Arthur's Cousin Catastrophe

Summary
Arthur does his best to avoid his annoying cousin, Mo, at a family reunion.

Plot
Arthur's family was getting ready to host their annual family reunion, known as the "ANNUAL READ FAMILY REUNION". Just then, Arthur's Aunt Loretta, Uncle Bud, and three cousins: Monique (who usually goes by the name of "Mo"), Ricky, and Loretta's daughter arrive at the front door.

Bud takes a picture of Arthur with his Supernova Solar Flash (a camera that X-rays people during the flash), and then Arthur politely welcomes them in. Loretta says that Mo has a surprise for Arthur and then Arthur has flashbacks to past reunions: When Arthur was 5 years old, Mo started the trouble by putting him on a lawn sprinkler; when Arthur was 6 years old, Mo practiced her judo moves on him; and when Arthur was 7 years old, Mo dressed him up as a baby by putting a bonnet on his head, a pacifier in his mouth, and a cloth diaper with a pin over his pants, and placing him in a pram, and everyone started laughing in front of him.

Arthur then screams and starts to run away from Mo, and Loretta states that Arthur has grown into an excitable boy. Outside, David starts the grill, and he begins to panic because he forgot to buy burgers and hot dogs. Jane then walks over to the grill carrying the burgers and hot dogs, and tells David that she bought the burgers and hot dogs, then takes over at the grill.

Arthur was hiding up in the tree to get away from Mo, who he claimed was ruining his life. As Arthur gets down from the tree, Cousin George was about to show Arthur a comic book called SPIDERGUY, but Arthur starts running away as Mo is about to go near him, so George shows the comic book to Mo instead.

As Jane is grilling, Loretta walks over to the grill and shows Jane the three-bladed spatula with a button, known as the Flip-o-matic. As Loretta is demonstrating the Flip-o-matic to Jane, she puts the three blades underneath the hamburgers, and then presses the button, but the hamburgers fly way up high in the air, and Loretta admits she set it too high.

Meanwhile, outside at Mr. Haney's house, Mr. Haney starts going outside the front door for a wonderful day, but three hamburgers land on his head, and he brushes them off with his bare hand and walks back into the house grumpily.

While Jane and Loretta are still grilling, David announces a sack race. Just then, he spots Arthur, who is still trying to hide from Mo, and asks very loudly through his megaphone if Arthur wants to join the sack race. Arthur starts stammering excuses about why he can't, but then he spots Mo approaching, so he grabs a sack and begins hopping extremely fast. Arthur ends up winning the race, leaving Uncle Bud marveling at how fast Arthur is "for a little fella", and Ricky angry about losing. Ricky then throws a fit for losing by throwing his cap off of his head and stomping on it while still in the sack.

Jane and Loretta continue lowering the notch of the Flip-o-matic to get the hamburgers done. Then everyone starts eating dinner. Grandma Thora and her son-in-law, Arthur's Uncle Sean, are having a conversation with her mother (Arthur, D.W., and Kate's great-grandmother).

Then they start having an egg race, and Arthur's great-grandmother wins the race, while some others lose the egg before they reach the goal. Then they play charades, but it's hard when Uncle Sean picks an obscure book nobody else knows. Then David dresses as a clown and tells everyone it is time to play a game of musical shoes, but everyone is tired. A thunderstorm arrives, it starts to rain very hard, and everyone gets back inside.

Later at night, Mo starts playing the piano, revealing that this was her surprise for Arthur, and that she had taken up playing the instrument because she saw Arthur doing so. Arthur tutors her a little in piano basics. When Arthur says he thought she wanted to decorate him like a Christmas tree, or send him into outer space, Mo replies, “You? You’re my favorite relative!”, and then adds the only reason she comes to these “dumb” reunions is so she can play with him.

They start playing a jazzy tune together, and then all their relatives come into the living room and dance along, and then David and Jane look on before turning to each other and kissing. Uncle Bud mentions that despite the weather, this has been a great reunion, and we then see that the storm has cleared up with a full moon in the starry sky.
