Jumbo Rat / New Friend Fiasco Lab Rat and Otto appear outside of a store that is selling jelly as she criticizes Otto's claims that it can be served with peanut butter. Using her Go-Big-or-Go-Small Ray, Lab Rat instructs Otto to use the green button to make her small only for Otto to make Lab Rat grow big by pushing the red button. Meanwhile, Amara gets a new product for the cats that involves dispensing cat treats as Bitsy declares herself too small to work it. Alerted of Lab Rat's rampage by Chibi, the SuperKitties in their Su-Purr Charged new suits must work to get Lab Rat back to small size. While climbing a tree, Ginny, Sparks, Buddy, and Bitsy meet a new cat named Ruby who is named after her ruby jewel and is the best climber. Ruby teaches Bitsy some tricks as Ginny is depressed that Ruby is teaching Bitsy instead of her. The SuperKitties get a call from Sam and Eddie about a new pet salon where animals go in and none of them are coming out. They discover that Cat Burglar and Grandma Catarina are responsible in order to make a gem-encrusted coat for Catarina. Ruby stumbles upon their scheme as well as Zsa Zsa. Now the SuperKitties must thwart Cat Burglar and Grandma Catarina's plot and rescue everyone.
