It's now summertime which gives the gang a chance to have fun in the pool. But Puppycorn is afraid of the deep end, so Unikitty and the rest try to help him and show him how cool the deep end is, but Master Frown is destined to make things worse to increase Puppycorn's fright.

After an accident, Puppycorn knocks his tooth out. After waiting for the Tooth Fairy, she doesn't show up, which leaves Unikitty to pose as the Tooth Fairy exclusively for Puppycorn. She soon takes up the opportunity to help the Tooth Fairy with her job along with her friends, which soon leads to disaster when they go too far.

The gang is planning a surprise for Puppycorn, so they spell things out when talking so he won't find out. Desperate to know what they're saying, Puppycorn finds a magic spell book that he thinks will help him learn to spell.

Richard finds the opportunity to take the others on a road trip, but soon the road trip turns haywire with bathroom breaks, stops to fix the tires and the van itself, interdimensional space/time travel, crumbs, road rage worriness, and an "evil truck" (in a reference to Duel).

After Puppycorn sees Unikitty do the most embarrassing thing ever, she forces him to forget by hooking him up to Dr. Fox's memory machine. While throwing away the bad memories and keeping the good ones, the gang look back at the past memories together (clips from past episodes in a clipshow style format).

Unikitty and Frown decide to have the first ever Election Day in the Unikingdom to see who would rule the kingdom as Princess. This eventually leads to a heated competition when Master Frown pretends to be nice and gives free things away in order to win the hearts of the citizens, while Unikitty tries to win her way, much to the disappointment of the citizens.

Unikitty and the gang (including Brock) decide to challenge themselves to stay up all night in order to meet the Sandman. After a night of activities, they start to notice that everything is not what it seems.

The gang arrives at Doki Diamond Funland, their favorite amusement park to ride the life-changing ride called The Sugar Crash. When Master Frown arrives to get everyone out of the line, Unikitty and the gang try and stop him.

Master Frown, Brock, and the gang finally get to ride the ride now that the line is empty. However when the ride turns into a never-ending nightmare when it keeps going on and on, the gang try to escape the ride before they're stuck on it forever.

When Puppycorn's toy dump truck goes "missing", Unikitty and Hawkodile turn into buddy cops and track it down, car hood sliding, stunt driving and delivering cool one liners along the way to crack the case while Richard is forced to be The Chief (even though he doesn't want to be).

When they think nature is gross and dangerous, Unikitty takes Dr. Fox, Rick, and Puppycorn through the woods to prove that it's not all that gross, while Hawkodile stays back and defends the van from creepy raccoons.

After destroying a group of chipmunks' tree, Hawkodile takes them under his care to train them into unstoppable fighting machines as Hawk's sensei trained him to be, but Unikitty believes this is wrong seeing as how the chipmunks are just kids.

On Valentine's Day, Hawkodile is planning to get Dr. Fox to be his valentine, but there's never a perfect moment to confess his love, so Unikitty and her friends are destined to help him find the perfect moment to confess to her.

When everyone starts experiencing dangerously low boredom levels, Dr. Fox introduces her new invention: the P.L.O.T. Device, which can make anything exciting happen, but it starts getting out of control when it's used too much.

When Toast is kidnapped at the party, Unikitty becomes a detective to track him down. On the way her and the gang run into secret passageways and clues.

When Frowntown goes sadder than usual, Unikitty and the others decide to deliver a rainbow to them to cheer them up, but Master Frown is destined to stop them in the style of Mad Max.

On Taco Tuesday, Unikitty and her friends are making the best tacos ever, but mysterious beeping fills the castle, giving the gang stress. Unikitty explains they're Bad Vibe Detectors that detect sadness and try to figure out who's sad, when they discover no one's sad, Unikitty takes them into therapy to test if they're upset.

After ordering food and it never comes, Dr. Fox introduces her latest invention: The Time Machine, which will let the gang make time go faster to get their order, but Father Time isn't happy about the use of time travel.

When the gang get tired of doing everything together, a laser tag game opens up in front of them out of nowhere. They soon find out Score Creeper (from Spoooooky Game) is in charge of this place, and pit them in a laser tag game against another team. During the game, Unikitty insists they work together to win, but the others would rather be a Lone Wolf.

When the gang get deserted on an island after an accident with a hot air balloon trip, they find comfort and enjoyment while Richard freaks out about chores at home.

At the Zoo, Master Frown pranks the gang, which prompts them to devise plans to prank him back. Unikitty wants to prank too, but doesn't seem to understand the concept of a prank when she believes they are too mean, pranking Master Frown nicely instead of in mean ways, which worries the rest of the gang.

When the gang notice Puppycorn is very accident-prone, Richard puts him in his old safety suit. It protects someone from any dangerous thing, but soon Puppycorn thinks that he can survive anything and starts doing very dangerous stunts.

A mountain in the Unikingdom becomes a volcano when it gets in a very bad mood, so the gang try to cheer it up by borrowing one of Feebee's most precious flowers, but Feebee herself isn't happy about it, and tries to direct the gang in a dangerous path to the volcano.

Unikitty and Puppycorn try to help Richard overcome his fear of flying in airplane while Hawkodile takes his flight test, but Richard can't seem to stop being afraid, no matter what.

At Unikingdom's Cheerleading Competition, Brock vows to make his dream of being a flyer on the cheer team a reality, but Really Old Edith and her team shakes it up and competes with them, making the competition heated.
