The Jar-B-Gone 3000

The "Jar-B-Gone 3000" was supposed to be Greg Heffley’s ticket to arcade fame. 🏎️💨
​Instead, it became a banana-splatting, olive-flinging weapon of mass destruction.

From the "Cyborg Chicken" prototype to the legendary Invention Fair incident that nearly took out Vice Principal Roy, see how Greg earned himself a one-way ticket to detention.

​Even Rodrick is impressed... but only because he wants to use the robot to pelt his fans with raw eggs. 🥁🥚
