If it's even possible Grian has gotten even better at flying. With his tail feathers, he can do things that would be impossible only using elytra.

He is currently on his way to the Shopping District, Xisuma has won Tag Two: Electric Boogaloo. It was Grian's job to take down the podium and to fill in the signup hole. As he finishes up with that he decides to go and check the barge.

As he starts collecting the profits TFC walks in and starts looking at some of the stock.

Grian welcomes him to his shop and the two start talking a bit. Grian finishes up collecting the profits and shoves the diamonds into the barrel he stores them in.

TFC hands Grian a few diamonds as he makes his purchases, "Thanks."

"It's not a problem," Grian says, hopping up onto the barrel.

TFC nods and heads for the door.

Grian waves as he leaves before turning to the wooden post in the middle of the barge. He grabs it wrapping his foot around it. He jumps up and clings on with his talons. He smiles as he clambers up to the rafters.

He settles himself in a corner, watching people come and go. After a while his communicator buzzes. Looking down he sees a message from Mumbo. It reads, "Where are you?"

As he answers he puffs up his tail feathers a bit as it is becoming night. "I'm at my shop, why?"

"Just checking, Iskall went full parent mode. They went over and couldn't find you."

"Oh, tell them sorry," Grian messages, he's still crouched in the rafters. He sets his Communicator down next to him and decides to head home. He checks his Elytra and grabs his communicator with his talons, flying off through his nether portal.

As he reaches his base he stretches and grabs his communicator letting Iskall know that he's at his house.

As Grian gets ready for bed he stretches, his back pooping several times. He climbs into his beds and falls asleep.

The next morning he wakes up with his back throbbing in pain. Groaning he reaches over and snags his communicator off the table. He calls Scar asking him to come over immediately.

A few minutes later Scar shows up and flies into Grian's room, "What's happened?"

Grian looks up at Scar, "Don't know my back hurts."

"Can you take off your shirt? I need to see your back," Scar requests, landing on Grian's bedsides table.

Grian nods softly and takes off his pajama shirt showing Scar his back.

"Wings," Scar says simply, "Looks like how mine did when they started growing," He pats the bone-like structures, "Do you want me to go ask Stress for some pain killers?"

"Yes please," Grian whispers, running his fingers through his tail feathers.

As Scar flies off to Stresses base he calls Mumbo and Iskall to come over to Grian's base.

By the time everyone gets there Grian is sleeping again. They look at each other before deciding to let him sleep. As they talk in hushed voices they see two little lumps form on Grian's back. Over the course of a few hours, the lumps turn into tiny little baby wings.

Meaning there completely bald, with pale flesh covering them. At some point, Grian wakes up, before learning what's happening and collapses back into his pillow. He's doing considerably better once Scar gives him the pain killer. So while his wings grow in he's talking to his friends.

Once the first stage of the wings growth finishes they look over what's happened so far, "So far you've gained a liking for seeds, near-perfect mimicry, gotten shorter, legs turned digitigrade, gotten little claws on your fingers, full-on talons for feet, tail feathers, feathers going up your spine and now wings that are probably about as big as one of Mumbo's hands," Scar recaps, landing atop Grian's head, "And you have feathers in your hair, when did that happen?"

"When I got the tail," Grian explains, looking at his back and attempting to wiggle his wings.

.......

The next morning Grian's wings are now as long as his arms, overnight muscles have grown and there is a thin layer of gray fuzzy down feathers on them.

As Grian wakes, the wings fuzz brushes against his back Causing him to mumble incoherently. Slowly realizing what had happened he rolls off his bed and stands up. Almost falling backward from the unexpected weight of the wings he grumbles incoherently and starts getting ready. When he pulls his sweater on he realizes a small problem.

His wings won't fit. Frustrated, he tosses his sweater aside and grabs one of the Mumbo for mayor shirts. Taking a pair of scissors he cuts slits in the back for the time being. Being very careful he's able to get his wings through the shirt.

Once he's Dressed he steps outside and is met face to face with Mumbo, who promptly drags him back inside.

"Mumbo, why?" Grian complains, pouting.

"You're growing wings. You should stay home," Mumbo protests as Grian attempts to scramble around him.

Mumbo closes the door and plucks Grian off the floor. He freezes, "Grian? Are you ok?"

At this Grian stops struggling and lets Mumbo place him on a chest, "Other than the whole bird thing. Yeah, I'm fine."

"Grian, you're way too light," Mumbo exclaims, worried for his friend.

"Oh, that's probably not good," Grian mumbles, poking at one of his wings.

Mumbo hums concerned, before running to grab the bird book that Joe had lent them, "Hollow bones, birds have hollow bones."

Grian smiles before wincing in pain. The wings have started growing again. Grian stumbles against the wall as they start twitching and shaking as they rapidly start growing.

Mumbo helps him over to his bed and he collapses face-first into the pillow.

In the span of a few hours the wings have doubled in length and are almost fifteen feet in length each with a total wingspan of thirty feet.

Almost as quickly as his tail feathers grew in his wings feathers grew in. The fluff that covers his wings is swiftly overtaken by small semiplume feathers.

As this happens Mumbo and Grian start reading the book that Joe let them borrow.

There are a few different kinds of feathers that appear to be growing, the first layer that everything else grows on top of is the down layer. These feathers are small and incredibly fluffy.

The next layer is the semiplume, it's another layer that is hidden by the other feathers. Like the down feathers, its job is to help keep the bird warm.

Then we have the contour feathers, they cover the body of the bird to help streamline the shape. The bottom half of the feather is fluffy and mostly lacking in form but the upper half is there to help waterproof. These feathers come in all sorts of colors, from helping to camouflage to brilliant reds.

The tail feathers, also called rectrices, have an interlocking microstructure that is similar to wing feathers. These feathers are arranged in a fan and help the birds steer as it flies.

Unlike most other feathers wing feathers aren't symmetrical the top is a bit shorter and is less flexible. Wing feathers are also known as remiges. These feathers are resistant to wind.

By the time Mumbo has finished reading the book with Grian, his wings have fully developed. The feathers on his wings are a golden brown much like his hair. And like his tail, they are speckled with many different colors.

.......

As Grian sits in his hobbit-hole waiting for Mumbo to come back an odd feeling washes over him. Not sure of what it means he shrugs it off. A few minutes later he gets hungry so he hops over to his food chest. He doesn't realize it but he's making quite chirping sounds as he looks.

This catches the attention of Professor Beak who screeches loudly as Grian picks up a few gold carrots.

Looking over at the bird Grian carefully sets the carrots on the Counter. Professor Beak flies over and pulls a salmon out of the food box.

Grian takes the fish, "You want me to eat this?"

Beak squawks and nods his head.

"Ok then," Grian mutters as he starts eating the fish.

A few hours later Iskall stops by to check up on how Grian's doing. When they enter the hole they are met with Grian huddled in a corner of the rafters sound asleep. Rolling their eyes, Iskall clambers up next to their friend.

Grian wakes up a few minutes later looking rather confused, "Hey Iskall."

"Grian, why are you sleeping up here?" They ask hopping off the rafters and holding their arm above their head so they don't smack into the ceiling.

Grian shrugs, "Just climbed up there and fell asleep, I guess."

Iskall seems to accept the answer and moves on, "Your wings look mega cool."

"Thank you, I can't move them that well but I'm figuring it out," Grian explains as his wings twitch a little from where they are folded neatly against his back.

"There are feathers all over your back, right?" Iskall asks as they create a slimeball and start fiddling with it.

"Yeah, they start at like the nape of my neck and just go all the way down to my tail," Grian says as he rolls his sweater up to show Iskall some of the feathers.

They continue talking and after a few hours, Iskall has to go pick Vee and Echo up from Joe who volunteered to watch them for a little bit while Iskall did some work on his tree.
