For  elcid. Blobby transformed Laguz anyone?

EDIT {10/3/17}: And now for the story, mainly written by me but with some changes made by Cid.

Vika, who was currently transformed into her raven form, flapped in front of an enemy mage. The raven proceeded to strike the mage with her beak. However, little did Vika know about this mage, he also had a unique tome in addition to the usual elemental one. The mage used it to cast some strange magic onto Vika, and as soon as the magic took effect, Vika found it harder to fly, coming to the realization that she was fattening up! The raven continued to pack on weight until she was unable to fly or move at all. Even though she couldn't move or attack for the time being, at least for now she'd make a lovely feathery bed!
