Still on the trail of how he and Elizabeth became geniuses, Toby Hyperfunctions, and creates a virtual memory for Russ, who has the "missing element" locked in his memory. But Elizabeth gets wind of the idea, and guessing that this will give Toby the power to remove her genius, she hacks into Russ' virtual memory, turning it into a virtual game. She enters the game herself to keep Russ away from the lab. Dina is forced to enter the game also to help Russ out, and finds herself monstered by Garth's giant dog. Russ' memory becomes a virtual battleground between Toby and Elizabeth; Elizabeth thinks she's won, but Toby pips her by crashing her hard drive. Toby at last uncovers the vital missing clue: the escaped frog that jumped across the MFE's keyboard.
