Full plot
Calvin and Hobbes wake up on a Saturday and prepare for an intense day of TV watching, only for his dad to shut off the TV and inform him that today is father-son day. Calvin rebukes him - after all, there's a hole in reality that must be contained! Unfortunately for him, his father refuses to believe him and hands him his bike helmet. Resigned, he tells Hobbes to stop the hole himself. Meanwhile, Brainstorm and Jack are doting about their lab when a call from Mother Brainstorm comes in. She tells Brainstorm that she and her husband are coming over, which sends him into a panic. As this is going on, Calvin is trying to ride his bike with his father, but Calvin's bicycle is once again acting up, and his father refuses to believe him. Eventually, he finds himself kidnapped by the bike, and both him and Dad crash. The third plotline is initiated when Hobbes asks the MTM about the black hole. The latter says that Calvin "was trying to install a special feature into me that would allow me to travel through time into different universes, but it didn't go through splendidly as he tried to splice the time vortex and an interdimensional portal together. The two forms of energy combined ripped a hole open in time and space." It grows stronger with time, and by 10:07 it'll destroy the entire universe if untamed. Thankfully, it's not too strong yet, and is currently invisibly sucking up light, air, and time. With that, the two try to close it - first by firing electricity at it, then by trying to close it with the MTM's extendable arms. Neither attempt works. The scene shifts to Brainstorm's lab, where we meet Father Brainstorm for the first time. He is a skinny man with green hair who seems like a perfectly nice guy. Unfortunately, not long after he shows up he starts acting like an embarrassing parent, revealing all of Brainstorm's embarrassing aspects, like his enormous stamp collection, which Jack finds very amusing. Brainstorm, naturally, is humiliated and quickly excuses himself to his room. There, he calms down and hopes that his father doesn't go in detail about his childhood... which he does. Meanwhile, Dad fixes his bike while reminiscing about his childhood while Calvin tries to placate his own. It doesn't go too well, of course. After this, Hobbes and the MTM try to stop the rupture by firing a different brand of lightning at it. All it does is make it wider, and another attempt to stop it makes it a perfect circle. Meanwhile, Father Brainstorm continues to tell everyone embarrassing stories about Brainstorm's past, eventually escalating to home movies as well - just as Jacqueline shows up, ready for the family dinner. Needless to say, Brainstorm is less happy than ever, and he sneaks out and flies out of the lab, eager to leave. As Calvin's dad decides to take his son along to fish, Hobbes and the MTM try to straight-up move the void, which only makes it really, really big. Calvin arrives at the booth, and he realizes that the person working there is Klein - more specifically, the one that worked at the movie theater. He shares the same sentiments on fishing as Calvin, but nonetheless Calvin's dad starts fishing. Meanwhile, Jack and Brainstorm's parents hang out at home, and when the former tries to find Frank he discovers the latter's absence. Shortly after, Calvin escapes the boring fishing trip in his cardboard box before meeting Frank, and the two discuss their fathers for a bit before Klein shows up again, delivering a little spiel on the importance of one's parents. Realizing the error of their ways, Calvin and Frank part ways - the former transmogrifies their lures into fish, and the latter returns home and directs the embarrassment at Sheila instead of himself. Meanwhile, Hobbes and the MTM try to deal with the void, their deadline almost up, when it suddenly closes itself up. As Calvin returns home from the trip, they decided to never speak of it again.
