Shasta and 7 Up are two white tigers introduced in "China-Man Begins".
Frank sees that Sammy gets featured on Channel 8's newest segment, Person of the Day, merely for owning two cats. Angered by this, Frank gets these two cats, hoping to follow in Sammy's footsteps. When Steve questions this, Frank claims the twosome is tamed but is proved wrong when they rampage through campus after being released. Shasta is killed by Falgot, while 7 Up kills a window washer after he and another one fall due to Frank's efforts to be person of the day.
