Franklin, the scientist of the gang, has a habit of making crazy inventions in his laboratory. Some of these inventions are a duplicating machine, robots, the Shock Avoidance System 2000, superglue, a smart umbrella, a washing machine so Blu couldn't escape from bathing, a shrinking pistol, hair-growth spray, a formula that turns someone into gelatin and time machines.
However, most of his inventions don't work, putting the gang in danger or troublesome situations.
