Taking Over Third Street Elementary
The scientists joined the Legion following Benedict's dismissal as Secretary of Education due to his attempt of abolishing recess throughout the country. Sharing his belief of abolishing recess to raise test scores, the scientists became involved in Benedict's next plot to get rid of summer vacation. To do so, Benedict gets his army of agents and ninjas to break into a U.S. military base, where they stole a tractor beam. They would later take over Third Street Elementary during the summer, as Benedict used to be principal until his firing in 1968 due to his anti-recess policy. With the school closed for the summer, the Legion used the school as a base for their own operations, and the scientists are tasked to perform numerous tests with the tractor beam under Fenwick's supervision.
As it turns out, Benedict plans to use the tractor beam to move the Moon at lunar perigee (the time when the Moon is closest to the Earth) to create permanent winter throughout the world so that student will have to stay in school, in hopes that it would raise test scores. Despite being in league with Benedict, Fenwick and several of the scientists (Dr. Lazenby and Dr. Steinheimer) argued that the plan would work better if they moved the beam to a more different location, but Benedict refuses to heed their advice; he even detained Dr. Rosenthal for his failure to fire up the beam due to bugs in the system. Benedict replaced Rosenthal with his reluctant second-in-command.
Defeat and Arrest
Eventually, T.J. Detweiller and his friends soon learned about the plot and that Benedict and his cohorts have captured their principal Peter Prickly. To that end, they get their fellow students to help reclaim the school; even the groundskeeper Muriel Finster arrived to help the students out by bringing in the teachers and staff. During the takeover, Fenwick and several of the scientists head over to the power room after the auditorium was blacked out by Gretchen. However, Gretchen anticipated this by locking them up in the room, but Benedict compromises this by having his remaining scientists to use a backup generator to get the power back in place.
Following the destruction of the tractor beam by Vince, the students and teachers cheered over their victory of saving summer vacation. The scientists were arrested and sent to prison along with Benedict and his other men for their crimes.
