It is Betty's thirteenth birthday, and Betty's family and friends are arranging a surprise birthday party. Meanwhile, after years of work, X-5 has managed to complete a working time machine. As a sign of the accomplishment, Admiral DeGill is ordered to present the time machine at the Galactic Council. However, this is a trap set by Maximus, who captures the time machine and travels into the future, with Sparky, X-5, Beatrixo, and Admiral DeGill as hostages. A downcast Betty and Noah, both having eluded capture, returns to Betty's birthday party, where a hand-me-down "re-gift" from Penelope inspires her to repair a prototype time machine (its only flaw being that it turned its occupants into gelatin) to full working order and travel to the future.
