At Canterlot High School, the Equestria Girls were helping clean up the graduation decorations. Some were using their animal forms. As Rainbow Dragon, she took down the banners with her flying. As Kanga Rare, she was using her pouch to store materials. Sunset Shimmer was using her unicorn magic.
"You know, Sunset," Rainbow Dragon said. "Have you tried turning into other types of creatures?"
"I'm fine with my original form," Sunset said. "Besides the rest of you are getting along with yours."
"Except Trixie," Sci-Twi said. "Have we asked her if she wants an animal form?"
"I saw her in the costume room trying on different costumes," Pinkie Pie said.
The girls head over to the costume room, where they find Trixie with costume racks of animal costumes.
"What's going on, Trixie," Sunset asked. "And what's with all the animal costumes?"
"This is how I'm deciding what my animal form would be," Trixie explained. "First I try on one of these costumes to see how I look then I transform into that animal."
"That's a good idea," Rarity comment. "Leave it to fashion to make you what you wear."
"Have you thought of some options," Sci-Twi asked.
Trixie shows some photos of herself dressed into different costumes and as the creatures of them as she explains, "I couldn't decide between a dragon like Rainbow Dash and a centaur." She uses her geode powers and dresses up in a new costume. "So, I tried both." She now uses her bracelet to transform into that creature. "A dragon centaur."
"That's looks awesome," Rainbow Dash comment.
"First time I hear of this type of creature," Sunset said.
"Maybe you girls should try too and have a second animal form," Trixie said. "Something that matches yourself. Like Fluttershy has wings when she ponies-up. So, you should try something with wings." She uses her magic on Fluttershy, dressing her up in a bee costume. "Like this."
"Good thinking," Fluttershy comment. "Maybe I might try one."
"I could try too," Rainbow Dash said. "Something with speed like me."
"I'm in," Pinkie Pie said, dressed in a turtle costume and popping out the shell.
"The rest of us are good with ours," Sci-Twi said.
"Besides," Applejack added as she's trying on a bat costume. "I would get out of control being a real bat. I'd suck my apples in my orchard dry."
"So, who want to try first," Sunset asked as the volunteers start thinking.
Choose Rainbow Dash
Out on the track field, the Mane cast were waiting for Rainbow Dash with for costume.
"So, what do you think as fast speed," Trixie asked.
"Well, there's a lot of fast animals," Sci-Twi said.
"Maybe she could be thinking about a type of bird," Fluttershy said. "Like a..."
Before she can finish, Rainbow Dash zooms by with her super speed until she stops and reveals her costume as she said, "Roadrunner!"
"Roadrunner," Sci-Twi asked.
"Roadrunner," Fluttershy said finishing her line.
"I know they don't fly," Rainbow Dash said. "But I bet they would have great speed."
She uses her bracelet and transforms into a real roadrunner. She looked a lot taller than a normal one (similar to the Looney Tune Road Runner).
"I don't think roadrunner are that tall," Fluttershy said.
"Maybe I was thinking of my size," Rainbow Runner said. "But let's see how this goes. Meep Meep!"
Rainbow Runner started running laps around the track. Then she goes around the school and into town. Sci-Twi sends her camera drone to watch her. The other girls watch as she zooms all over town.
"Now that's my kind of roadrunner," Pinkie Pie comment.
"Defiantly her animal," Sunset added.
"Just hope she doesn't come behind and surprises us," Applejack said.
Rainbow Runner does so and went, "Meep Meep!" This made Applejack jumped in surprise and falls back into the others. In a flash, they accidently triggered their bracelets that causes them to switch forms: Applecrane, Rarideer, Fluttercat, Puppy Pie and Kanga Twi. Sunset, who wasn't bumped, gave Rainbow Runner a look.
"Sorry," she said.
However, they all share a laugh.
Choose Fluttershy
Fluttershy takes her friends to a river, where she will show her costume, hiding under her robes.
"I was thinking of Trixie's advice of flying animals," Fluttershy said. "So, I'm trying a bird."
"I'm guessing a duck," Rainbow Dash asked.
"A goose," Sunset asked.
"Or a swan," Sci-Twi asked.
"How can you tell," Fluttershy asked.
She notices she's wearing webbed feet as Applejack said, "Lucky guess."
"I thought of the birds for flying and swimming," Fluttershy said. She takes off her robe and reveals she's wearing a duck costume. "And one that goes with my color."
She transforms into a real duck with her bracelet and tries her swimming ability. She starts to enjoy herself as she now tries flying. Other ducks join her in a V formation. The other girls admire her new form.
"I'll say she's better than as a deer," Sunset said.
"And would have a "quack" about it," Pinkie said joking.
Choose Pinkie Pie
In the costume room, Pinkie Pie is rummaging through animal costumes and tries on each one, trying to find one she's interested. She tries on a flamingo and comment, "Tried it."
Changing to a giraffe costume, "Too tall."
Changing to a skunk costume, "Too stinky."
Changing to an armadillo costume, "Maybe later."
Finally, she finds one she's interested and comment, "Why not try being your pet?"
Outside, the other girls wait on Pinkie as Rainbow Dash said, "She been in there almost an hour, how hard can it be to choose?"
"Which ever one that would match her," Sci-Twi said.
"Maybe," Pinkie said coming out. "But I thought of being like my pet, Gummy."
The girls were surprised to see that Pinkie was dressed in an alligator costume. Sunset looked concerned as she asked, "Uh, Pinkie, isn't your pet just a stuffed toy?"
"True," Pinkie said. "But the pony me's Gummy is a real gator. With no teeth." She transforms into a real alligator with her bracelet and has normal teeth. "And I guess I can make this form less dangerous."
"At least you do have sharp teeth," Fluttershy said.
"I would go with an armadillo," Rainbow Dash comment. "If you like bouncing a lot, you should try being rolled up as a ball."
"Maybe next time," Pinkie Gator said.
