Professor Granville tasks Hiro with dogsitting her quirky trio of pooches while she's off at a STEM conference for the day.
Tropes in this episode:
- Affectionate Gesture to the Head: Cass ruffles Hiro's hair after she makes him take the dogsitting job and takes his games away until he is finished.
- Attack of the 50-Foot Whatever: Curie briefly becomes huge as a result of her swallowing one of Honey Lemon's chem-balls.
- Babysitting Episode: Except with Hiro looking after dogs instead of human babies.
- Big Friendly Dog: Granville's sheepdog Curie, when she isn't busy chewing everything she can get her mouth on.
- Brick Joke: Granville's chihuahua, Oppenheimer, steals Baron Von Steamer's mechanical arm while Wasabi and Fred are returning the other items he fetched. Baron Von Steamer walks into the café to retrieve it at the end of the episode, and takes the remaining money Hiro has as well.
- Continuity Nod: Hiro's time as a bot-fighter is referenced when Cass refers to the dogsitting job as Hiro's first summer job "that's not illegal", followed by a brief shot of Hiro having his mugshot taken.
- "Could Have Avoided This!" Plot: Hiro repeatedly refuses to read Granville's care manual, resulting in the dogs becoming more than he can handle. After he finally reads it and reins them in with its help, the rest of the team isn't happy to learn there was a manual that spelled out exactly how to control the dogs.
- On the other hand, the trouble could also have been avoided if Granville had taken maybe an extra minute or 2 before leaving to explain the dogs quirks and not downplayed them or even left a more simple list of instructions for just one day of dogsitting. Adding to this, Granville put the Mr. Pip instruction in the middle of the manual instead of on or closer to the front page.
- Dinosaur Doggie Bone: Oppenheimer fetches a dinosaur bone from the San Fransokyo Museum of Art.
- Fictional Video Game: The Wormhole series, which Hiro and Fred are both shown to be into, the segment opening with Hiro playing one of the games in the Lucky Cat Cafe. Hiro hopes to use the dogsitting money Granville will pay him to buy the upcoming third installment.
- Floorboard Failure: After chasing Fermi to an abandoned restaurant, Hiro and Baymax get stuck in the floor when trying to get ahold of him.
- Good-Times Montage: After Hiro and Baymax lose track of him, Fermi has one as he runs wild through San Fransokyo and meets Felony Carl and Globby, but it slowly turns into a Lost Love Montage as he begins to miss his squeaky crab.
- Grin of Audacity: Fermi smirks very smugly whenever he's about to disappear on Hiro.
- Incredible Shrinking Dog: GoGo and Honey Lemon only catch a break with Curie when she eats a chem-ball that makes her tiny.
- Hypocrite: Fred when he says "yeah, that's fair" along with Go Go, Honey Lemon, and Wasabi after Baron Steamer steals the last of Hiro's dogsitting money after they've all taken their cuts, considering he asked Hiro to help him with beating Wormhole 2 even after being told Hiro had a summer job, apparently had no problem with Hiro bringing the dogs over to his house, and that it was his idea to call the rest of the team for help when the trouble started, which Hiro probably went along with because it seemed like the fastest way of resolving things.
- Idiot Ball: It's made clear at the end the rest of the team didn't know Hiro had a manual until after retrieving Fermi, even though Baymax held it in full view of the others when Hiro asked them for help.
- Jerkass Ball: Go Go's initial refusal to help comes across as this due to the fact that this occurs before she knows about Granville's manual.
- Just One More Level!: Hiro stayed up late to finish Wormhole 1 and Wormhole 2 in preparation for the release of Wormhole 3.
- Laser-Guided Karma: After all the trouble Hiro unnecessarily put them through by not reading the manual sooner (which led to Fred losing his copy of Wormhole 2 and Honey Lemon breaking her glasses), the rest of the team all rightfully take a cut of his dogsitting money, with the final bit he intended to use for Wormhole 3 being pinched by Baron Von Steamer as compensation for having to track down one of his arms after it was "fetched" by Oppenheimer, which everyone but Hiro states is fair. On the up side for Hiro, with his task now done, Cass will return his copies of Wormhole 1 and Wormhole 2 which she had temporarily confiscated while he was watching the dogs to avoid distractions. Of course, as pointed out in YMMV, this might be an averted trope depending on your interpretation.
- Missed Him by That Much: Cass goes inside the cafe just as Fred calls Hiro for his help to finish Wormhole 2. Had she waited a little longer, she could have ensured Hiro would focus solely on the dogs.
- Mister Muffykins: Granville's chihuahua, Oppenheimer.
- Muscles Are Meaningless: Granville can easily scoop up her two larger dogs with one arm each and carry them without even breaking stride.
- Never My Fault: While Hiro should have read through at least part of the manual, Honey Lemon and Go Go don't acknowledge that the trouble with Curie was the result of Honey Lemon carelessly leaving her chem-purse unattended and in reach of a dog she saw had a chewing habit before Hiro assigned Curie to them (Honey Lemon having similarly left her chem purse unattended in "Big Roommates 2" which led to it being stolen by Globby. Adding to this, Honey Lemon's glasses only got broken because Go Go put her glasses back on her face while she was struggling to tear off the chem ball goop covering her eyes, which led to Honey ripping her glasses in half.
- Non-Indicative Name: The Wormhole series of games, based on an offscreen comment by Fred, are actually about a hole full of worms, not the hypothetical spatial phenomenon of the same name.
- Pint-Size Powerhouse: Oppenheimer, carrying things much larger than he is as he plays fetch.
- Puppy-Dog Eyes: Hiro uses this on GoGo to convince her and the others to help him with the dogs.
- Read the Freaking Manual: Professor Granville wrote a very thick book about how to take care of her dogs. Hiro loses control of the dogs because he didn't bother reading the book. Granted, the job was last minute and the manual is very big.
- Security Blanket: Fermi has one in the form of his crab squeaky toy, Mr. Pip.
- Series Continuity Error: Wasabi's dog allergy from "Steamer's Revenge" is never mentioned and he is not shown to suffer any ill effects from the dogs or the stuff Oppenheimer fetched.
- So Proud of You: Cass tells Hiro she is pround of him for having a legal summer job.
- Tempting Fate: After Hiro's friends take their cuts of his dogsitting money, he says he still has enough to buy Wormhole 3. Cue Baron Von Steamer showing up to reclaim his mechanical arm and take Hiro's remaining money for his troubles.
- Theme Naming: Befitting a woman like Granville, all of her dogs are named after famous scientists.
- Troll: Every time Hiro catches up with Fermi after he runs away, Fermi smirks while effortlessly evading capture.
- Tropey, Come Home: The segment is about Fermi running away from Hiro's watch, and for the latter to find him before Granville comes back.
- What Could Possibly Go Wrong?: Hiro thinks he can both look after the dogs and help Fred with beating the final boss of Wormhole 2, he is soon proven wrong. Though, as pointed elsewhere on this page, you can make the case the trouble wasn't entirely his fault.
