The mishaps never end as TJ's "helpers" from the 23rd century—Tuna and Herby—continue to study TJ as she learns the valuable lessons she'll need to become a future world leader. In Oops!, TJ learns the importance of speaking and thinking well of people even when they are difficult, thanks to the Thought Broadcaster Pen, which exposes the thoughts of everyone it hits. As usual, Tuna and Herby's attempts to fix the pen only make things worse—now all of TJ's thoughts become reality! As she fights not to return meanness to others (and to clean up the disasters her thoughts cause, like turning whiny TV star Hesper Breakahart into a giant baby), TJ learns from her dad a little more about how her mother handled things: She kept reminding herself that each of us is God's creation. And no matter how mean people may be, we all need to be loved. The same message also unfolds through a side story of classmate Chad Steel learning to treat a mean boy better.
