Silverborn?

Chapter 10

Three hours and multiple curses later, unit 919 trooped out of hometrain in various states off disarray.
Thaddea was nearly unrecognisable as she had multiple different animal body parts instead of her own.
Her arms were that of an ostrich, her mouth changed for a puffin beak, her curly red hair was now an avalanche of bright orange snakes.
Morrigan couldn't hold anything without turning into smoke, and Hawthorne would make random train noises between sentences.

"Looks like you had a good time!" Miss Cheery says, barely containing her laughter.
"Are you trying to torture us? CHOO CHOO" Hawthorns asks incredulously.
At this Miss Cheery bursts out in a fit of giggles. She doubles over, clutching her stomach and laughing heartily. What feels like hours later to Hawthorne (it was three minutes), she finally pulls herself together. Straightening, she wipes the tears from her eyes.
"I'm sorry," Miss Cheery laughs, "run down to the teaching hospital and they'll get you all sorted out."
Thaddea didn't need telling twice, before Miss Cheery could even finish Thaddea was dashing towards the exit. In her eagerness she didn't notice Mahir's outstretched leg in her path, in a split second she was face down on the floor, grabbing Mahir's ankle and pulling him down on top of her as a sign of retaliation.
