DREAMZzz: Trials of the Dream Chasers

After sharing an incredible dream, Mateo and his sister, Izzie, realize the Dream World is real when Mateo's comic book hero, Z-Blob, comes alive and follows them back to Brooklyn. But when Mateo's ex-best friend, Cooper, is captured in the Dream World by evil nightmare creatures and can't wake up, Mateo and Izzie discover there are Waking World consequences to what happens in their dreams.

In defiance of the evil Night Hunter and his grimspawn, Mateo and Izzie free Cooper only to need a rescue of their own. Luckily, their science teacher, Mr. Oz, is actually a secret agent of the Night Bureau. In the heat of battle, Mateo wakes up and brings a night terror back with him to Brooklyn, which he and his friends must defeat without their Dream World powers. 

To craft their own hourglasses and become official Dream Chasers for the Night Bureau, Mateo and his friends must defeat a giant sand guardian and enter the Dream Forge before the Nightmare King's forces destroy it. But when there's a dreamer in need, the kids must choose. Will they face the forge and become more powerful dreamers, or will they help their friend?

As the clock runs out to face the Dream Forge, Mateo and his friends enlist the help of the mysterious Dream Bandit and her abilities to manipulate time. Mr. Oz and Albert defend the forge from a grimspawn onslaught while the Dream Chaser hopefuls enter the forge and face their deepest fears. But they must hurry: if the forge is destroyed before they finish, they may never become Dream Chasers!

The search for the Sandman leads Mateo and the others to the tallest mountain in the Dream World, Pillows Peak. Only the Sandman can repair Lunia's hourglass, which the Nightmare King will stop at nothing to control. When a friendly competition turns spiteful, the Nightmare King is alerted to the kids' location and orders an assault on the mountain.

A surprise visit from the Chief Inspector Strick of the Night Bureau forces Mateo to hide Z-Blob. When the lovable Dream World anomaly escapes to explore Brooklyn, Mateo must track him down before anyone sees him. Meanwhile, while the gang handles Strick, who was zapped by a device that makes a person live out their last dream, making Strick act like a toddler and cause havoc in the observatory.

Logan and Mateo are facing off over who will ask Zoey to be on their Sheep Week team, and Logan will do anything to win. When they have a face-off in the video game based Cyber Realm, Logan accepts a cheat code from a stranger, which corrupts the entire realm! With the help of the Cyber Realm Guardian, the kids must stop the virus or lose the realm to the Nightmare King forever.

Backs to the wall with a surprise math test and the opening round of the Sheep Week games, Mateo and his friends track down their math teacher, Ms. Putnam, in the Dream World to find the test's answer sheet. But it turns out that within sweet little Ms. Putnam is a ginormous inner rage just waiting to be let loose.

Desperate to prove his worth, Logan is blindsided when he delivers Lunia's hourglass to Lance, who is really the Nightmare King! Held hostage in the Shadowkeep, Logan makes a surprising new friend in the grimspawn Sneak, until they are forced to do battle. Meanwhile, Mateo and the others are in a battle of their own on the soccer pitch in the Sheep Week finals.

It's all hands-on deck to rescue Logan from the clutches of the Nightmare King, but Oz and the kids quickly learn that there are more dangerous creatures lurking in the Grim Realm than just grimspawn. In the Shadowkeep, Logan is sprung from his prison cell by his grimspawn ally, Sneak. But why would a grimspawn risk it all to save an agent of the Night Bureau?

A wave of nightmares washes over the school, causing Coach Jeffries to mandate students reveal their dreams to him for interpretation. When Mateo and his friends try to investigate this issue in the Dream World, they realize they are locked in their dream landing by a mysterious dome! Their only hope is for Zoey and Z-Blob to team up and liberate them from their dream landing.

With Albert, the logical side of Mr. Oz, imprisoned by the Night Hunter, Mr. Oz is not in the right frame of mind to stop Agent Strick when she captures Z-Blob and places tracking devices on the kids. Mateo and his friends must rescue their teammates, but when Strick threatens to turn them back into normal dreamers, do they dare take the risk?

Mateo steps out of his comfort zone and allows Cooper to read his comic book, but he quickly regrets it when the comic goes missing. Izzie takes on the case as a Private Investigator, but when she digs a little too deep, she uncovers a new crime! Meanwhile, Nova, the head of the Insomniacs, is busy trying to crack the mystery of the Dream World.

The hunt for the Sandman, the only one who can repair Lunia's hourglass, leads to a crash landing in the Murky Realm. The kids begin to forget the most important aspects of who they are as they fight off the vicious sirens that patrol the foggy landscape. They are offered refuge by the ever-creepy Neverwitch; but can she be trusted? After all, this is the place where memories go to die...

Witnessing the plight of Nova and the Insomniacs, Izzie convinces the others to find them in the Dream World and bring them to the Candy Realm where they can have the sweetest dream ever! But when they stumble upon some grimspawn also seeking a vacation from the world of nightmares, they soon realize the Night Hunter is close behind. Meanwhile, Cooper tries to activate Lunia's hourglass.

Lunia's activated hourglass guides the Dream Chasers to Castle Nocturnia, the fortress of the Dream Keeper. Within its walls lies the key to defeating the Nightmare King, but so does a great creature of myth who has been charged with protecting the castle's secrets from unworthy dreamers. The kids must prove themselves to be worthy or they'll fall at the hands of the beast!

Castle Nocturnia is under attack by the full force of the Nightmare King! The Dream Chasers must defend the castle long enough to reveal Lunia's records, which are hidden in the stained-glass windows of the castle. If they can't activate the windows before the castle falls, they may lose their chance to learn how to defeat the Nightmare King!

Using his corruptive energy on Z-Blob, the Nightmare King begins to open a rift to the Waking World, but to stabilize it he requires the help of a dream crafter using Lunia's hourglass. When Mateo lacks the power to activate Lunia's stained-glass window because of his grief over Z-Blob's capture, he presses Oz to reveal what happened in the final battle between the Nightmare King and Lunia.

The fall festival becomes the perfect hunting grounds for the night terror that Izzie brought back to Brooklyn. When the Night Hunter tracks Mateo down in the Waking World and threatens his family, he decides to travel to the Dream World and confront the Nightmare King alone while his friends desperately try to save the festival guests from being corrupted by the night terror.

The Nightmare King intends to capture the Waking World as he invades the fall festival with his nightmare army. The Dream Chasers must make their final stand and put a stop to the Nightmare King once and for all. But without back up from the Night Bureau, the kids must rely on each other as they fight to reunite the two halves of Z-Blob and close the rift to the Dream World.
