Cue the Oh, Crap! moments.
Well, for whatever reason may be, the heroes have survived, but now have somehow been separated during the quest. Friends, Family, or just people that are happy to see each other. When they finally meet back up, they take a moment to celebrate their reunion, but it must be cut short. They are quickly reminded that they have no time to spare and must continue on with their goal.
This trope is used to describe a situation that arises when a character or group of characters accomplish something worth celebrating over, but the moment is cut short when someone or something, usually the Only Sane Man, reminds them that they're not out of the woods just yet... Or they just simply forget. This is very much Truth in Television in athletic contests - sometimes someone showboats a bit too soon and winds up blowing their chance at victory because of it.
This is mostly a comedy trope, though sometimes played seriously. Sometimes a disaster could be averted if someone had just remembered it.
- In one episode of Pani Poni Dash!, the miserable rabbit Mesoussa has a time bomb placed on him by a adorable and polite "Jinx in Training" who wants him to be unhappy. Becky and a few of her students start trying to figure out how to defuse the bomb over the course of the episode. With less than a minute left before the bomb goes off, Becky arrives just in time to tell Mesoussa that they figured out how to remove it. Mesoussa is overjoyed, everyone starts praising Becky for a job well done, and everyone just starts celebrating at the accomplishment... *BOOM!*

- In The Legend of Zelda: Ocarina of Time, Link storms Ganondorf's Tower, defeats him, and then escapes the Collapsing Lair with Zelda when the villain tries to pull a Taking You with Me.

When Link goes to investigate, a Not Quite Dead Ganondorf emerges from the rubble and transforms into Ganon, the true Final Boss.

- In XCOM: Enemy Unknown, after Strike One successfully assaults the aliens' terrestrial base and defeats the Sectoid Commander leading it, XCOM HQ is full of cheering personnel and triumphant music plays. When Dr. Vahlen asks Central Officer Bradford whether the victory celebration is "a bit premature at this juncture," he replies that "We just neutralized their central command, we've got no other alerts on the entire system, and we took out their leader. In my book, that's a win." Vahlen just gives him a Disapproving Look before walking off. Sure enough, the Sectoid Commander wasn't the only one of its kind or the highest-ranking part of the aliens' forces, and the war is far from over. And with the Enemy Within expansion, less than a month after you destroy their base, the aliens launch their own assault on XCOM's headquarters in the Base Defense mission.

- The villain in The Real Ghostbusters episode "Slimer Come Home" (named "Mr. Ugly" by the heroes in-story and "Ghash" in the Storyboards and Script files) is a massive poltergeist who becomes far stronger by absorbing the power of other poltergeists. The heroes manage to bust him after he combines with dozens of them, but then, as Egon tells them in near panic, the ghost trap now has far more ghosts in it than it was designed to hold, meaning they have to floor it back to the firehouse and transfer them to the containment unit before they break free explosively.
