Junie B. Jones and That Meanie Jim's Birthday is the 6th Junie B. Jones book. It is in the kindergarten series.
Jim turned six and had a birthday party in class. His mom bought chocolate cake and milk and ice cream. Jim gets wound up chocolate milk squirts out his nose and Lucille lost her appetite. Junie B claimed she did to but snuck out of her seat and ate both her and Lucille's piece. After that Lucille was eating her ice cream and Junie B showed her how to eat ice cream like a little lady but accidentally slops it onto her dress which is dry clean only.
On the bus Junie B and Grace talk about their own party and Jim butts his head into their business and announces his upcoming party on Saturday. He then gets mad at Junie B deciding to invite everyone except her making her Unset.
At home Junie B talks to Grandma Miller about it and her mom too. She plans to do her own party six months earlier and not invite Jim as revenge. But they say no to that idea. The next day Junie B wants to run away but her parents won't let her and force her to come to school. Her dad said to pretend she don't care about the party. That same morning Grampa Miller calls and invits Junie B to come help fix the toilet. At recess Jim passes out invites. When Crybaby William receives his Junie B snatches it away but gets in trouble. In class Junie B gets in trouble for talking to Lucille and Jim laughs causing her to twist his head. The teacher sends her to the office.
At the office, Principal has Junie B tell her what happens and calls Jim down. He has Jim apologize to her and give her and invitation.
On Saturday, the day of the party, her mom makes her go to the mall and buy Jim a present which was a tool belt. Once they get home, Junie B won't give up her tool belt and doesn't want to take a bath. She nails her door causing her mom to get really really mad. Her father too.
After that, she decides not to go, returns the tool belt and goes to Grampa Miller's to fix the toilet.
- Junie B. was born on June 1st (as mentioned in Junie B. Jones is a Graduation Girl), six months after Jim, meaning that Jim must have been born on or around December 1st. It also means Jim is older than Junie B, assuming they were born in different years.
- This is Jim's biggest role, although his role in Junie B. Jones and the Mushy Gushy Valentime comes at a close second. This is also Jim's biggest antagonistic role.
