Synopsis:
While on the road, the Have Cots (Ruby, Leafy, Teardrop, Balloony, Lollipop, Gelatin and Bubble) and Nots (Blocky, Firey, Loser, Taco, Flower, Spongy and Woody) discuss the new job Leafy has accepted as a gym teacher. Ruby is reluctant about his decision because of the eerie weather and location.

As they pull up to a school they realize that it is the neighboring Boldon Military School. The Grimsand School Ruby has a contract with is much more frightening and spooky. Ruby gets flung across the moat to the door and is the first to enter the school and meet their pet dog Lunar who sprays fire at Ruby.

The Have Cots and Nots enter the Grimsand school as a drawbridge lowers and they are able to walk across. They meet Lunar and Miss Grimsand, discussing Leafy's new job and contract. They also meet a floating hand which helps them with their luggage. One by one the girl-ghouls are met and introduce themselves to them. Zella, Witch, Alien, Blob, Kaiju, Creature, Gargoyle, Medusa, Wilma, Jasmyn, Kylie and finally Maddie. The Have Cots and Nots by this time are already trying to leave the school and terminate Leafy's contract. Leafy who is terrified, mentions how the "girls" are actually girl-ghouls.

The girl-ghouls discuss their problem of not ever winning the volleyball championship against their rivals the Boldon Cadets next door and The Have Cots and Nots agrees to stay and help, starting with early morning exercises the following day. Ruby starts noticing things not right about the Grimsand school such as a pet piranha in the goldfish tank. Early morning exercises start with ballet while the neighboring Boldon Cadets are beginning their warm-up exercises as well. The Cadets spy The Have Cots and Nots with a telescope and take note of the new coaches at Grimsand. They soon loose their volleyball to Lunar after a cadet serves the ball hard and loses it. The cadets aren't able to practice for a while.

Continuing morning exercises, the Grimsand girls go for a morning jog and meet up with Lunar who is burying the cadet's volleyball. The Grimsand girls stop for rotten apples while Ruby and Leafy stick out their tongues in disgust. Meanwhile, the Boldon Cadets are working on a water balloon bazooka which they plan to use to retrieve their volleyball but Lunar ends up returning it anyway before they get it working correctly. The gangs meets giant fly-traps in the garden as well as all the rotten food in the garden which the Grimsand girls like. In the garden Ruby sees crystal balls which have been planted their to spy on the Grimsand girls, the first clue that they are being watched by Diamanté, an evil sorceress who wants to use the girls to become "the most powerful witch in monster-dom".

Colonel Boldon visits Grimsand School in order to set the time for their annual volleyball tournament. Miss Grimsand offers him fungus fudge and toadstool tea which he eats and drinks in disgust as he comments that it tastes moldy. The Have Cots and Nots is introduced to Colonel Boldon and they plan to play at 1400 hours which Balloony clarifies as 2:00 p.m. The girl ghouls warm-up with "scare-o-robics" and "deep shrieking" exercises and scare the Boldon cadets with the loud screaming. Meanwhile the cadets are warming up with standard stretches and pushups. Colonel Boldon gives the cadets a short pep-talk and tells them that they've "gotta win".

The girls finish their exercises with loosening their muscles and a short swim in the Grimsand moat. Lunar blow-dries them off right before the match. Miss Grimsand calls Smith over to repair the Grimsand net and boundary lines. Soon the game ready to begin!

Jasmyn begins the game with a couple good serves. Soon they are at 10-10 tied. Then Boldon takes the lead after Kylie goes through the net. Next, Maddie serves the ball and scores a point, Grimsand now taking the lead. Boldon implants a control device into the volleyball so they can control how the ball moves. They use a remote to make Maddie's serve look bad and they take control of the ball. Boldon takes the lead again until Teardrop accidentally swallows the ball's remote control and squirts ketchup at the cadet who was serving. Grimsand gets the next serve by Wilma and they catch back up to Boldon. Diamanté is shown to be watching the game in anticipation. Wilma spikes the ball off the back of Kylie and Zella gives the final serve. The remote control in Teardrop's belly gets triggered and the ball moves back into the Boldon's side of the court. Grimsand wins and Maddie gets the trophy for her mummy case.

The Grimsand girls start setting up a halloween party, excited that they have won the annual volleyball game. Miss Grimsand bakes brownies and caterpillar cookies. The Grimsand girls talk about how their parents plan to attend the party. The Have Cots and Nots get scared as the monsters begin to arrive and they go hide in a secluded room. Diamanté watches the monsters arrive through a crystal ball. The parents meet The Have Cots and Nots anyway and believe they run away from them simply because they are gym teachers trying to stay in shape. Soon they've all met and Tanis's father thanks them for "making Maddie feel like a winner".

The Grimsand girls present gifts they have made for their parents such a lemon juicer for werewolf parents, a bat-robe for vampire parents and a portable shockman for Frankenstein parents. Diamanté watches the whole time through a crystal ball, saying that "soon the party will be over". Kylie plays a song with the floating hand as an accompaniment. The parents leave after the party is over.

Diamanté and Grim Megadrop plan to hypnotize Leafy. They send a bat out to go find Leafy and hypnotize him. Ruby sees the bat as it tries to enter but Leafy doesn't see it. It hides in the window shade and later above Leafy's bed. The bat weaves webbed-headphones which Diamanté uses to talk to and hypnotize Leafy. She tells Leafy to take the Grimsand girls to the Lurky Swamp for a jog, to which he accepts.

The following morning, the Boldon Cadets wake to a homemade alarm clock and discuss their upcoming field trip to the Lurky Swamp, the same day Leafy is planning to go. Meanwhile, the Grimsand girls all get ready for their field trip as well. Miss Grimsand waves goodbye.

At the swamp, Diamanté's sidekick the Grim Megadrop awaits to capture the Grimsand girls. Leafy isn't in a trance anymore but is still excited to go for a jog at the bog. Wilma is the first to meet up with Grim Megadrop and his bats. Wilma dodged the attacks and did not get brainwashed. Grim Megadrop was worried Diamanté was gonna kill him.

Balloony asks Leafy how he thought of going to Lurky Swamp. Leafy can't recall except that it might have been a dream. They don't watch where they are going and soon all then get stuck in a swamp full of alligators. The Have Cots and Nots realize that the area is much more dangerous than they'd previously thought. Zella transforms into a bat in order to save them from the alligators. Meanwhile, the Boldon Cadets are out hiking nearby and fall into quicksand. Maddie and Jasmyn see the boys sinking and help them out of the quicksand with a tree trunk.

The Have Cots and Nots begin to look for the girls, realizing that they haven't seen them around. Zella sees the Tarantulas and asked Witch for some help. Ruby runs into Grim Megadrop and Lunar saves him with his fire breath as Grim Megadrop runs off.

The rest of the girls meet up with Wilma and helped them fight off the Tarantulas. Grim Megadrop retreated and reported back to Diamanté. Diamanté was furious at first, but then, she had an evil plan. After hearing Diamanté's evil laughed, the Boldon Cadets tell thes of the supposed way to defeat Diamanté, by letting her fall to her death.

After entering by way of Kaiju's tail as a key, the gang splits up to search the place. They were suddenly double-crossed by Grim Megadrop who led them into a trap. Grim Megadrop warns them of the Grande Dweller. creature who lives in the well tunnel. The creature lurches toward them.

Gelatin starts a ball game with the Grande Dweller. and tricks him into making a ladder for them to escape the well tunnel. Grim Megadrop changes Ruby into a frog as a last-ditch effort to scare them into conformity. Ruby as a frog, runs for his life, while the Grimsand Girls made a plan to get rid of him. Grim Megadrop was tricked into falling down the well and eaten by the Grande Dweller.. Witch changes Ruby back to normal. Diamanté appears and confronts thes, Boldon Cadets, and Grimsand Girls, changing into a devil.

After confusing Diamanté by banging several different gongs, Gelatin's presence is revealed to Diamanté. Zella tackles Diamanté to the ground, allowing Ruby and Gelatin enough time to escape, but the devil chases them to a statue across a pit of lava. Diamanté is killed within the rock, and it plummets onto a large stone in the lava below.

The Boldon Cadets return back up in the nick of time to save them all by flying away in the homemade helicopter. Back at Grimsand, everyone has thrown a huge party to celebrate the success. Balloony does a rap. Soon Leafy and Ruby are introduced to a new set of students and they run away in terror. Balloony says goodbye to Lunar and she, Lollipop, and Gelatin follow. As the walk away, the Grimsand girls wave goodbye from the porch of the school. The Have Cots and Nots howl a loud Grimsand goodbye and walk off into the moonlight.
