Wanting to get rid of Queen Delightful and to conquer Jollywood as well as tricking The 7D, Hildy and Grim Gloom have to rely on magical transformations and disguises to carry on their plans carefully. Sometimes they also can be transformed by their enemies or through other means. This article list all the Glooms' magical transformations.
On the eve of the Jolly Berry Pie Festival, the Glooms brew a mind-control potion to take over the kingdom. They have to get one last ingredient -- whiskers from Grumpy's beard. So they went to a Jolly Berry grove where the rest of 7D are picking berries as Jolly Berry trees to get close to Grumpy.
After flying into the air by Sneezy and falling to the ground, Grim (by delay) turned themselves into birds. Hildy ordered him to change themselves back, and she became a frog, a toilet, and finally a box containing her human self. Grim then transformed back to being human.
The Glooms are at the 7D's cottage as hedges to be behind a window to get Grumpy's whiskers. But Sneezy blows them away into the air again. Grim turns him and Hildy into ostriches, not realizing that ostriches cannot fly as they slammed into the ground below.
In their final attempt, Hildy reduces herself to the size of a dwarf to blend in with the Jolly Berry Pie Festival crowd. She finally obtains Grumpy's whiskers, but failed to add it to their potion because of a barrage of flying pies.
Hildy had turned Delightful ugly so she won't get another award for being the fairest in the land as well as obtaining the Jollywood Gemstone Wand. Delightful wins again because of her love for her people, but that doesn't stop Hildy from snatching the wand away from the Queen. Hildy's actions forces the wand to transform her into an ugly monster.
While performing a magic trick, Grim accidentally turned himself into a frog. Hildy has to turn him back to human but she doesn't like anything icky, so she believes that the Love Stone will cure him instead of having to kiss him.
As buzzards, the Glooms dispense rocks into Delightful's organ pipes. Now that the queen's pipe organ is in need of repair, the disguised Glooms convince her to buy one of theirs that contains a note that will turn the people of Jollywood into stone when played.
After witnessing a dragon attacking the Jollywood village, Hildy wants a dragon of her own to do the same. Unable to find one, she temporarily made Grim a dragon to scare off the villagers. However, the dragon returned and whisked Grim away, thinking that he's her baby.
Grim gave Hildy a shape-shifting ring as a present. By shaking the ring, Hildy can transform into any animal she desires. But Hildy loses it at the carnival (while becoming a mouse in the process), which eventually got swallowed by Delightful's pet fish Teensy. In the end, she got the ring back and became human again, but dropped it into the ocean.
Grim is presented with a very powerful wand -- which can read the minds of anyone and making it come true -- from Hildy. They plan to sabotage they Heroes' Day concert at the Jollywood Bowl, but the wand was swapped with Happy's baton at a road collision. Sir Yipsalot eventually got possession of the wand; and as the Glooms chased him, the pooch thinks of pickles and a pile of them stopped the Glooms. Then they became cats.
Hildy and Grim become a mop and bucket, respectively, to stay undetected from the 7D so they steal away from them the le fromage de grosse pew so drive away Delightful our of her castle. Hildy is being used to clean the deck of the 7D's boat. Later when the 7D came ashore to Piquant Island, Hildy transforms into an anchor (she then goes underwater) while Grim becomes a buoy. In the end when their plan failed at the castle, Hildy angrily turns Grim back into a bucket.
