Little Bear's Adventures of My Little Pony: Equestria Girls - Legend of the Everfree

Little Bear's Adventures of My Little Pony: Equestria Games - Legend of the Everfree is the twelfth upcoming Little Bear/MLP:FIM crossover to be made by Hiatt Grey.

Plot
The students of Canterlot High School attend a field trip to Camp Everfree, a nature camp owned by Gloriosa Daisy and her brother, Timber Spruce. During the bus ride, transfer student Twilight Sparkle has a nightmare of being overtaken by "Midnight Sparkle", a malevolent alter ego of herself produced while temporarily corrupted with magic from the alternate world of Equestria. Her friend Sunset Shimmer is supportive, relating through her own similar experience with transforming into a demon. Shortly upon arrival at the camp, Twilight develops telekinetic powers, which she worries is a sign of Midnight Sparkle's lingering presence.

That night, Timber tells a campfire story about a forest spirit named Gaea Everfree[n 1]  being angered by the camp's construction and threatening to unleash a plague of natural disasters upon it. The next day, a sailboat crashes into a dock the campers are building to use as a fashion show runway. The terrified campers spot a trail of glittering gem dust in the water that matches the description of Gaea's presence in Timber's story, convincing them that Gaea is real. Twilight, however, believes her own magic to be responsible for the accident and distances herself from her friends.

Later, amidst an apparent earthquake and another sighting of gem dust, Twilight's friends begin developing their own unique superhuman abilities, which they find they can only use within the camp's boundaries. Now believing her magic is infecting her friends, Twilight prepares to run away from camp. Sunset follows Twilight into the woods and, discovering her own power of telepathic empathy, convinces her to stay. As Timber leads them back to the camp, Sunset notices gem dust falling from his pocket and suspects him of staging Gaea's attacks. She later overhears him arguing with Gloriosa to abandon what Sunset assumes to be the camp. Remembering his earlier statements of longing for urban life, Sunset concludes that Timber means to shut the camp down by terrorizing the campers.

Sunset brings Twilight and Spike with her to investigate a nearby cave kept off-limits by Timber, where they find a deposit of geodes infused with Equestrian magic. The three are confronted by Gloriosa, who reveals herself to be the true cause of the natural disasters. Sunset learns through her visions that Gloriosa, desperate to prevent the camp's foreclosure, has been wearing the geodes as a necklace to harness their power, with the "disasters" resulting from her reckless attempts at using magic to improve the campers's experience; Timber, anticipating this, invented the story of Gaea Everfree to cover for her.

Gloriosa adds more geodes to the necklace and is corrupted by their power, taking on an appearance resembling Gaea. Crashing the campers' fashion show rehearsal, Gloriosa enacts her intent to "protect" them by trapping the entire camp in a giant bramble cage. When her friends fail to stop Gloriosa's rampage, they encourage Twilight to embrace her own magic to assist. Following one final struggle against Midnight Sparkle, Twilight asserts control of herself and takes the geode necklace apart, freeing Gloriosa from its influence. The geodes turn into pendants for Twilight and each of her friends, who gain new magical forms and restore the camp. Still faced with the camp's foreclosure, the girls realize that the geodes are the source of their powers, which they use to organize a last-minute fundraiser ball that is held within the cave. Their plan is a success, attracting a large crowd of former campers and saving the camp.

In a post-credits scene, the girls finally restore the dock after it has been wrecked several times, but Pinkie Pie accidentally destroys it again with her powers, leaving the group in shock.
