On The Planet of Easily Frightened People, the frighten beings easily surrender and Bob uses the evolving device to turn one of the beings into a blob of protoplasmic goo.

Jim and Peter arrive and notice that Bob looks different. Bob uses his tail to whack away Jim's blaster and uses the evolving device on the earthworm and puppy. As a result, Jim and Peter become dimwitted Neanderthal versions of themselves while Bob evolves into a human. Bob orders the socks to eat Jim and Peter but because they are "man eating socks", Bob orders them to chew them up and leaves, taunting Jim as he going to rule the universe as Jim is to dimwitted stop him.

As Jim and Peter are cornered by the socks, Princess What's-Her-Name appears and screams so loud that in summons moths to chase the socks away.

Later in Terlawk, Jim and Peter try to adjust to dimwitted nature and can't do ordinary tasks such as eating, getting dressed or even deciding to what to watch on T.V. The Princess learns from a news channel that Earth is being attacked by Bob. The Princess turns off the TV and tell Jim and Peter that Bob is attacking Earth, however Jim and Peter explain that they're too dimwitted to stop him. Finally, having enough, the Princess tells them to shut up and to take charge of their own lives. Later, in Washington, DC, the Princess explains that Bob's War-Fish is very powerful. Jim wonders what one of the buttons on his Pocket Rocket does and the trio crash lands straight into the War- Fish. Bob warmly welcomes them and devolves the Princess into a ladybug. Bob then evolves into a super-human and now has the ability to know everything, thanks to his gigantic brain. In addition to his enhanced intelligence, he has the power to shoot lasers from his brain. He gloats about how universal conquest will now be child's play as he laughs manically.

While Bob is distracted laughing, Jim and Peter fall out the War-Fish and crash land in a pudding museum. So, all world's countries join forces together in order to combat Bob in a very epic battle.

In response, Bob uses the uses the evolving device on Peter a second time, turning the puppy into a trilobite that only says "doinky". Meanwhile, Bob transforms back into his normal goldfish form and was correct about fish being the highest form of life. But, Bob loses all of his evolutionary upgrades, much his dismay. Jim then tries to shoot his blaster at Bob, but the latter explains to the former that he's holding the wrong way.

As he tries to readjust his blaster, he throws it at the evolving device which releases all of the evolutionary energy causing Number 4, Jim, Peter and the Princess to revert back to their normal selves. Peter tells them that Bob and Number 4 are planning to attack. Jim tries to destroy the War-Fish by shooting at it with his blaster. It works for a while, but the blaster runs out of plasma and Bob fires a laser from his War-Fish, which chars Jim. The Princess snaps Jim out his dazed trace and they think of another plan to distract Bob. After a quick trip to France, Jim throws Jauque Theropy at the War-Fish and begins hypnotizing Bob and Number 4 with his trolling voice.
