Everything's going great for Freddy and the Funkhauser family: Theodore, Wally, Curly, Ziggy, Si, and Meese -- Freddy's French fry pals who came to life thanks to Freddy's knack for science -- have helped them face up to their mean rivals, the Spankers.

Trouble is, big bully Adam Spanker isn't about to let Freddy get the upper hand. As Freddy hatches a plan to set Adam straight, he discovers the lab of long-lost scientist Silas Finklebean, along with instructions on how to build a time machine. With Finklebean's help, Freddy and the Fries are determined to prove themselves to Adam once again.
