Gas Or Fail is the twelfth episode of the third season of Henry Danger. It premiered on March 25, 2017 to an audience of 1.79 million viewers.


Henry arrives at the Man Cave to see Ray and Schwoz where he learns that they're preparing for Ray's indestructibility test. Schwoz manned the machine that is used to launch the balls towards Henry for him to hit the balls with the electro-bat to hit Ray, and Schwoz receives the results per hit. However, before they began the test, Henry requested to get five yai-tons, but Ray was uninterested in the meantime. As Henry continues hitting the balls, he explains to Ray that he is unable to attend work because of his school's standardized test session. On the very last ball, Henry accidentally hits Schwoz, making him fall down and faint, for not paying attention. Henry and Ray then proceed to leave the Man Cave to get yai-tons after deciding that Schwoz was perfectly fine. At school, Ms. Shapen is preparing the standardized test session by asking the class if they had their test booklets ready. She then asks the class if they know why the test is very important, but they all say no. Because of this, she requests that Henry and Jasper stand up to tell the class, which they then proceed to sit down. As soon as the class begins their test, a siren goes off. While Ms. Shapen quickly tries to convince that they should continue taking their test, the class requests that she should turn on the TV for any news report, in which they learn that there's a gas leak somewhere in Swellview. Henry asks Ms. Shapen to go to the bathroom, only to have her decline.

Meanwhile, Ray enters underground as Captain Man to fix the gas pipe while calling Schwoz. As they continue having their phone conversation, Ray falls down when his rope suddenly breaks. Ray asks Schwoz to triple-beep Henry so that he can help save Ray. As soon as Henry's watch made a triple-beep sound, Jasper quickly takes the blame by saying that it came from his pacemaker. Henry once again asks Ms. Shapen to go to the bathroom, attempting to convince her that he really needed to go. She lets Henry go, but only if he comes back three minutes later. Upon visiting the bathroom, Henry hears the sound of a drill and encounters Schwoz where he then tells Henry that Ray needs saving. Henry quickly begs to differ, but Schwoz comes up with a plan to create a hologram of Henry pretending to take a test by having him sit down and use a pencil. Schwoz helps Henry enter through the hole to find Ray. After leaving the bathroom, Schwoz texts Charlotte and Jasper that Ms. Shapen needs to conduct a three minute break. After the students exit the class, Schwoz then activates the hologram of Henry in his exact seat, with Charlotte and Jasper watching the process.

Using the tyson drill, Henry finds Ray and helps him exit the area where the gas pipe was found. They head back to Ms. Shapen's classroom after Henry moans about being hurt. In class, Ms. Shapen asks every student for their test booklets without knowing that Henry is in hologram form. Captain Man then enters the classroom to walk towards Ms. Shapen and ask for a kiss in order to distract her from seeing Henry coming in to disable the hologram. After kissing, Captain Man then drops Ms. Shapen to leave, and Henry offers his test booklet to her as she lays on the floor in shock.
