"Brain's Biggest Blunder" is the second half of the seventh episode in the sixteenth season of Arthur.


When Brain gets teamed with Buster and Binky in the annual Arithmattack competition, he immediately enrolls Buster in binomial boot camp. Can Brain transform Buster into a mathematic marvel? Or will he be forced to eat humble pi?[4]


The intro begins with Brain showing the viewers his new fridgerator and his old fridgerators when there was a monster inside a cage and Brain ends the intro by putting his hands on the screen.

The episode begins in Mr. Ratburn's class with Buster who got a math problem wrong and Brain who got the problem right, so he trains him for the Arithmattack competition against Prunella's team. Steve's team lost, but Brain's team makes it to the Arithmattack finals against Prunella's team. But Buster got offended at Brain for his bad tutorial session that he left the cafeteria. So Binky tutored him well through imagination for a couple days, and his team won the Arithmattack competition.



  • In this segment, Steve speaks for the first time.
