Tippy sent his smaller, younger self back in time to find out where George and Harold disappeared to. Because of this, three Tippys existed at once: "Big Tippy," "Tiny Tippy," and "Slightly Younger Tiny Tippy." They traveled back in time after George and Harold, during which Tiny Tippy and Slightly Younger Tiny Tippy decided they didn't like being bossed around, so they snuck out and traveled through time to get the Goosy-Grow 4000 (ironically causing role reversal between the boy who often noticed the events and his mother who was skeptical about them). Tiny Tippy had Slightly Younger Tiny Tippy use it to restore him to his normal size and then again to make him bigger, calling himself "Supa Mega Tippy." However he refused to use the Goosy-Grow 4000 on Slightly Younger Tiny Tippy and immediately traveled back to the Mesozoic Era.

Supa Mega Tippy and the others traveled to the caveman age, where Slightly Younger Tiny Tippy tampered with his giant counterpart's freeze beam so that it couldn't be turned off.

After George and Harold got the cavemen to help fight against him, causing damage to him and his robot, so Supa Mega Tippy tried to freeze them, but as his freeze beam wouldn't turn off(which was due to Slightly Younger Tippy sabotaging the device and its emergency shutoff), and Slightly Younger Tiny Tippy permanently turned the Goosy-Grow 4000 on with the help of some gum to repeatedly increase his size until he accidentally drops it. This causes the Goosy-Grow 4000 to zap the ice, which causes the ice to rapidly spread across the planet, starting the Ice Age and freezing Supa Mega Tippy to death. George and Harold untied Mr. Krupp and turned him into Captain Underpants, who moved the cavemen to a safe area but was turned back to Mr. Krupp by Slightly Younger Tiny Tippy, who took him, George, Harold, Crackers, and Sulu, and traveled thirty years into the future from their time.

George and Harold turned Mr. Krupp and his future counterpart into Captain Underpants, who beat up Slightly Younger Tiny Tippy. When it looks like they would win, Tippy activates his nuclear bomb which he modified to destroy the entire galaxy. Crackers and Sulu got on board his robot and sent it back in time to before the universe existed. In the darkness, the bomb exploded, killing Slightly Younger Tiny Tippy and creating the universe with the Big Bang (or "Big Ka-Bloosh Theory").

Thus, all three of his deaths caused the major events of the universe to take place.
