The thick, sticky silence of a prehistoric evening settled over the Croods’ cave. Inside, Grug was attempting a new form of entertainment: shadow puppets.

“Gah! Sky demons!” Grug screamed, throwing a blanket over his own head.

He lifted it over his head to smash it. But just as he did, the TV flickered to a commercial: a bright, happy jingle for “Mammoth-Burger! You’ll have a KILLER meal!”

“New rock!” Thunk cheered, hitting it with a club. It didn't break.

Eep’s eyes went wide. “They have an Eep who fights a giant pterodactyl every single episode!”

Instead, the flat rock flickered to life. A blinding square of light appeared, showing… themselves.

His shadow looked like a lumpy boulder. Eep, Thunk, Sandy, and even Gran stared with dead-eyed boredom. Ugga tried to smile, but her eye twitched.

Suddenly, a low WHOOOOSH echoed from outside. A strange, flat object had fallen from a rent in the sky. It was sleek, black, and had a faint, humming glow. On its back, in strange symbols, were the words: THE CROODS – SEASON 3 – STREAMING NOW.

“Behold!” Grug grunted, holding his massive hands in front of the fire. “The story of the Brave Mammoth Who Obeyed His Father and Did Not Lick the Glowing Blue Moss! ”

But on the glowing rock, the Croods were moving. They were singing a catchy, repetitive chant: “We’re the Croods! We hunt and we squawk! We’ll hit a thing with a rock and then we’ll ROCK-talk!”

On day four, Grug finally spoke. “I have a new rule,” he said, ripping the glowing rock from the wall. “NO. MORE. TV.”
