Season 1

Eli Shane wins his battles and gets a new slug. It's time for the finals, but Eli is beaten with a dark slug given to his opponent by Dr Thaddius Blakk.

The gang has to trade one of Eli's prized his slugs for some new gear, but when Eli has second thoughts and goes back to get his slug, they learn its been sold to Dr. Blakk!

When the hooligang enters the Quiet Lawn Cavern and think no one is tough enough to stand up to them, they get proven wrong by Eli and his gang.

When Eli and the gang enter the Deadweed cavern, they discover a huge amount of El Diablus Nacho, the Dark Water Dr Blakk uses to brainwash innocent slugs.

Eli wants to enter the Slug Run, despite being told he isn't experienced enough. He finds himself up against some tough opponents, including Vance Volt, who works for Blakk.

When even Kord can't find a way to fix what's wrong with the new upgrades to the Shane Gang's Mecha Beasts, it's time to go to the source: the wondrous Mecha Forge! Hoping to find the cause of the glitch, the gang instead uncovers a huge conspiracy--hatched by Dr. Blakk!

Eli doesn't believe in ghosts -- until he enters Deadweed cavern! But it turns out Eli's first instinct was right. What lurks inside Deadweed is far more evil than ghosts, its El Diablus Nacho, after a supply of the dangerous Dark Water that Dr. Blakk uses to turn innocent slugs into Ghouls.

A short cut takes the Shane Gang through the territory of the Shadow Clan -- and try as they might not to, they are discovered and captured by the mysterious creatures. Just when it looks like our heroes are done for, they are helped out of this jam by a most unlikely savior.

Pronto is thrown in jail on trumped-up charges by a corrupt judge, and the only chance to break him out is Eli making a one-in-a-million trick shot. Only one slinger in all of Slugterra can help Eli make a shot like that—Mario Bravado. Finding the formerly-great-but-now-washed-up Mario is easy. Getting him to help is something else entirely.

Long thought to be merely a legend, an Enigmo Slug has finally been spotted. The bidding is high for this, the rarest of all slugs, and so is the competition to be the first grab it! Eli and the gang actually beat Slugterra's most vicious slug hunter to the prize--only to find that the hunter is now hunting them!

After a wild ride on the mysterious Flumes, the Underriver that runs beneath all the Slugterra, the Shane gang find themselves dropped into a sea cavern, where they are promptly shanghaied into the crew of the Pirate Captain Malvolio Drake.

A fun trip to the mall cavern turns un-deadly when the place is over run by the zombie-like victims of the Zombus slug. With Pronto zombified (not entirely a bad thing, the others kind of like this new, quieter, more monosyllabic Pronto), the rest of the Shane Gang must find the mysterious Mr. Saturday who controls the Zombus slugs -- and find a way to stop him.

The four members of the Shane Gang think they've found the fifth in Twist, a street-smart kid who volunteers his help when the gang needs it most on a mission gone wrong. However, Twist harbors a dark secret that could doom the mission — and the Shane Gang.

Along with Twist, the Shane Gang plan to rob a train carrying the last of Dr. Blakk's Dark Water. They work out the plan and are trapped by Diablos Nacho. Kord realises that Twist works for Dr. Blakk.

Avalanched inside a frozen cavern, the Shane Gang can't figure out which is worse: being trapped with a vicious Ice Ogre that only gets bigger the more you shoot it? Or needing to work with The Hooligang to get out?

A thief breaks into the Shane Gang HQ looking for the fabled "Shane Treasure" — a portion of which she believes belongs to her. The thief escapes with nothing, but Eli does manage to find a treasure chest. To unlock it, and when they finally open the box, what's inside is not at all what they were expecting..

Notorious con man Gar Revelle has many convinced he has discovered the way to a secret land... a land that seems to be the surface! Eli uncovers the truth—Gar is getting his information from a coded Shane diary.

A mysterious slugslinging master appears for the first time in 20 years. Though old, this slinger is an amazing battler—incredibly fast and the master of an unstoppable slinging technique. Eli, Kord, Trixie and Pronto all want to study with the master and learn this awesome move.

Blakk has hired Brutale to build a Deep Water Rig to drill for Dark Water at the bottom of the Cavern Sea. Needing some water-breathing labor for the job, Brutale steals Marvolio Drake's reptilian pirate crew. Desperate to get his men back, Drake forms an unlikely alliance with the Shane Gang, who are just as desperate to shut the Dark Water rig down.

Using some stolen Shadow Clan tech, Dana Por is able slip in and out of any cavern in Slugterra—and rob them blind! But when she makes the mistake of stealing from Dr. Blakk, Eli is the only one who can protect her from The Gentleman, a suave but deadly mercenary Blakk hires to take back what was stolen from him—and bring back the scalp of the girl who stole it!

Lumino cavern is under attack! A swarm of Neurotox ghoul slugs have created a massive toxic cloud that's attacking the residents. The Shane Gang must brave an inescapable maze called the Cavern of Time to locate Blite, Blite is a deadly maniac, whose reign of terror ended only after Will Shane trapped him in the Cavern of Time. All these years, Blite has been dreaming of getting revenge on the Shane. So Eli better be ready!

Eli and Kord have been trying to create a fusion shot which consists of two slugs being shot at the same time using both of their powers. In order to make it work, they’ll need to travel to Scrap Heap, a junk yard cavern protected by Boss Ember and his Scrap Force.

Eli and the Shane Gang become trapped in caverns underneath SlugTerra and discover a new type of danger that is threatening to escape.

The Shane Gang's been captured by the zombifying Mr. Saturday. Locked up in Stalagmite 17, they are helpless as Dr. Blakk begins the trip there to collect them. Only one hope remains the two members of the Shane Gang Saturday didn't capture: Pronto and Burpy. Can this mismatched pair pull off an impressive prison break?

The Shane Gang follow Diablos Nacho to Molemound - the Molenoid home cavern. Pronto doesn't want to go - and not because he's in trouble. It turns out Pronto is the rightful KING of the Molenoids. He's been ducking the crown for years since the king's main responsibility is settling arguments and fixing leaky plumbing. But Pronto must play king for a day while the Shane Gang follows Nacho into the great Molenoid library to stop him from taking a valuable map. Meanwhile, Pronto faces an unwelcome challenge for the throne by his Life! Long! Nemesis! Seedo.

The Shane Gang must use every bit of skill they have when they are lured into an elaborate game by a Twisted villain calling himself the Game Master.

Burpy is sick, and the only thing that will cure him is a trip to the Lightwell - a mysterious, hidden power source only slugs (and the Shadow Clan) know the way to. Burpy can't make it on his own, so Eli vows to take him there. He convinces the Shadow Clan to point the way, but the journey is fraught with peril. Meanwhile the rest of the Shane Gang must fight side by side with the Shadow Clan when Blakk's minions attack.

When a mysterious creature begins draining the energy from all the slugs in a distant cavern, the residents offer a rich reward to whoever can stop it.

Dr. Blakk has been captured! Now it's up to the Shane Gang to transport him to Stalagmite 17, the only prison that can hold him. To do so, they're going to need some serious speed.

Eli and the gang attempt a daring rescue mission to free Redhook, but along the way discover Blakk has a much more sinister plan in the works.

Dr. Blakk has succeeded in creating a gap in the magical slug-energy barrier that protects Slugterra, opening the way for the evil Darkbane to tunnel their way up from the Dark Caverns. Eli and the Shane gang must stop this at any cost. Now armed with a selection of upgraded slugs, blasters and armor, they take the battle to Dr. Blakk's front door. While his team slugs it out against Dr. Blakk's minions, Eli takes on Blakk himself once and for all!
