RAT 215 PERRY20 EPISODE 73d94d2f-e17b-429b-b1c9-6be6e1271234 10003436 220x124
Mission Creek High is too old of a school, since the equipment is too old, and the textbooks seem to date back to the 1700s-1800s. Leo and Chase decide to do something to update the schools system, which leads to Mr. Davenport to want to help. They first say no, that his ego would get in the way. They eventually gave in. The school is updated with everything being electronic, and it's great for everyone, until Mr. Davenport made a robotic version of Principal Perry, because he wanted a wing with his name on it in the school. Everyone begins to hate Leo and Chase, which leads to them reprogramming Robo Perry before the school board sees it. Meanwhile, Adam and Bree try to prove that the new foreign exchange student, Allister, is a bionic spy, because Marcus was the new kid, and he turned out to be a bionic spy. They end up freaking him out and accidentally hurting him. The final straw comes when Adam accidentally picks up a whole shelf of weights. Since Chase and Leo tampered with Robo Perry, she reset to the original military use: search and destroy. She is attacking everyone on the school board and Principal Perry, which almost leads to Adam, Bree, and Chase revealing their bionics due to Davenport's orders, but before they can, Perry tackles Robo Perry, and rips her head off, so their secret is safe. In the end, it turns out Allister is not a bionic spy (due to evidence that made Adam and Bree think so, such as him being able to do different accents perfectly like Bree's vocal manipulation, and catches things with perfect reflexes, and uses terms that sound like he's an android), and all of the dodge balls Adam threw at him made him lose his memory of anything after dodge ball. Allister then shows Adam and Bree his dodge ball team made of exchange students. They throw balls at Adam and Bree and walk off.

She tries, but ends up getting caught in her own prank by Chase tricking her. Davenport tries to help her, only for Leo's Grandma to be caught in the crossfire. Donald then becomes her assistant.

Things quickly go back to bad when Rose gets the scooter. While Janelle distracts Rose, Leo programs the scooter's GPS for "home", allowing him and Janelle to spend time together. When Leo gets home, Donald asks where Rose is, and Leo says she should be home. They find out it was accidentally calibrated for Mission Creek, Illinois instead of California.
