Sandy is finally old enough to join Grug and Eep for the annual Daddy Daughter Day and Grug couldn’t be more excited. But when Sandy struggles to fit in with Grug and Eep’s traditions, Grug has second thoughts.

When Phil learns no one on the farm thinks he's fun, he sets out to prove them all wrong... by building a crazy amusement park.

Believing he doesn't fit in on the farm, Chunky (aided by the other pets) leaves home to follow the distant call of another death cat. The kids set off to bring him back home. Note: Gran narrates the story.

When Guy invents a primitive skateboard, Eep and Dawn have a blast trying new tricks.

When Eep and Dawn find a stranded egg, they eagerly take it in as their new pet, but when they learn the egg is not what it seems, they have to return it before it becomes dangerous.

When Phil detects a meteor is hurtling towards the farm, the Bettermans and Croods must decide how to spend their last day on earth.

Phil and Guy try to disprove the Croods' belief that leaving offerings to the fire moon will prevent bad luck. But when their efforts seem to cause a series of mishaps, they'll have to retrieve the horn of a dangerous ramaconda to turn their luck around.

Hwam returns with news of a utopian cave community, accidentally reigniting the argument between the Croods and Bettermans. As the Croods journey to Caveana and the Bettermans adjust to life without them, the parents deny how much they miss each other.

After a back-breaking day of farm chores, all Grug and Phil want is a slice of pie. But when there is only one slice left, both Grug and Phil argue that they deserve it more. To prove who works harder, Grug and Phil switch chores on the farm for a day.

Grug accidentally reveals a subterranean cave beneath the treehouse. When Phil can't convince Hope, Grug, and Ugga that the treehouse is more impressive than the new cave, he sets out to destroy the cave.

When Grug saves Hope's life during a dangerous mountainside tartichoke harvest, rather than feeling grateful, Hope is desperate to save Grug's life in order to not be indebted to him.

When Hope allows Dawn to borrow her favorite bracelet, Dawn is determined to prove she is responsible. But when an accident leads to the bracelet being stuck in an Eegle's nest, Dawn, Eep, and Guy must retrieve the bracelet before Hope finds out.

After Thunk and Guy tell Eep and Dawn a campfire story of Gorgwatch, a hideous monster who roams the woods, the girls are terrified.

When Grug thinks his forehead looks too big in Ugga's family portrait, she strives to make the painting disappear.

The kids take their "Dare Game" too far, causing Grug, Ugga, Phil and Hope to forbid them from playing it. But when the adults also get hooked on the game, the kids must convince them to stop before someone gets hurt.

Thunk goes missing after the Thunder Sisters dismiss his help during a battle. The Thunder Sisters, and Grug, Phil, and Guy's newly formed "Thunder Sifters" search on and off the farm for Thunk.

When the Bettermans invite the Croods to join their family game night, two things become clear: Phil needs to win and Grug hates to lose.

When Grug overhears Thunk accidentally call Phil "Dad", he tries to reconnect with Thunk by taking him to the natural spectacle known as "Big Shine."

When the parents find their precious outhouse destroyed, they perform a "trouble trial" to find the culprit. To prove their innocence, each kid provides their own explanation for the outhouse's destruction.

Ugga has a secret - she's taking Eep to "flop with the bulrusses" - a fun and dangerous pastime Ugga enjoyed as a teen. Ugga's excitement fades when Hope invites herself and Dawn along.

Eep loves action and adventure - it's in her blood. But when Eep starts adventuring in her sleep, she has to try to find the cause of her new sleep walking to avoid ending up in dangerous situations.

When a freak lightning strike turns Thunk into a genius, Phil is thrilled to have someone likeminded on the farm, until the farm residents start asking Thunk for help with problems on the farm instead of him.

Tired of the farm's feud with the neighboring punch monkeys, Ugga arranges a punch summit where the Bettermans and Croods will stay in the punch monkey village to learn how to all get along.

Determined for Grug and Guy to bond, Eep plans a hunt for the three of them. But when Eep sneakily makes it appear that Guy saved Grug from a charging bearacuda, the two believe Guy is a master hunter, and head to hunt a dangerous scorpulion.

Gran announces it's time for a Thunder Sister retreat at Camp Thunder to strengthen their team building skills, but Gran takes it too far when she puts the sisters through a dangerous trial.
