The Big Dig/Wedding Crashers.The Big Dig: While trying to dig a new private swimming pool in Galactic Guardian headquarters, the Bangoons unearth a rare and valuable opal. Because it can also be dangerous, Betty is tasked with its proper storage, but Admiral DeGill also tells her to keep the mission secret. Returning to the surface, Noah, who had been with Betty when she was summoned alone, chastises Betty over leaving him in the dark; Betty reluctantly tells her mission to him, but also warns him to keep it a secret. Later at school, Noah shares the secret to Sparky, who, being a gossiper, spreads the news to everyone he finds. The gold rush mentality spreads, attracting the attentions of Max Sr. and Hopper the Chopper, who journey to Earth, intending to take the treasures for themselves. When Betty gets word of the news spreading, she quickly chastises Noah for telling Sparky, before receiving orders to stop Hopper. However, she fails to either stop Hopper or Max Sr., who had arrived shortly after, in separate attacks. Back at headquarters, the situation is getting worse: treasure diggers have nearly dug their way into the roof of headquarters...
Wedding Crashers: Betty's grandparents have arranged for a "just for fun" remarriage ceremony at the form, to be organized by Sparky. After nearly forgetting about the invitations, Sparky sends out invitations to Zulia, Spindly Tam, and also Auntie Matter, the villainous sister to Beatrixo. Later, Betty is concerned that she cannot afford to purchase a special locket for her grandmother as a wedding gift, though Sparky and X-5 agree to help her raise the money to buy the locket. At the wedding, both Betty's parents and the whole Galactic Guardian organization (which Betty's mother assumes to be all odd-looking relatives from the opposite side of the family) are in attendance for the ceremony; but it is soon interrupted by Auntie Matter, who abducts Jimmy. As Auntie Matter retreats into deep space, Betty and Beatrixo pursue her on the Century Warbler; however, it was just a ruse to lead the two away as Auntie Matter returns to Earth with Jimmy. Auntie Matter plots to push Jimmy into a black hole that acts as her source of power, which would grant Jimmy the same powers and allow the pair to elope. Betty and Beatrixo return in time to free Jimmy, who then tells Auntie Matter that he does not love her. Auntie Matter is eventually defeated when Betty overloads the black hole with a large bouquet that spews out confetti, which causes Auntie Matter to lose her powers. With the wedding back in order, Betty apologizes to Beatrixo about her present, which was lost in the black hole. Beatrixo forgives her, saying that her presence is more than enough as a present.
