”Feather vs. Itsuki” is a slowly ongoing (and also probably canceled) TF battle between Feather and his childhood friend, Itsuki. What started as a simple prank transformed into a shapeshifting rivalry in which the two Yoshis take turns surprising each other with sudden transformations, many of which are mind-altering or difficult to undo.
Now that "Fish Scales" has caught up to the point that this mini-series would've started, I feel fine to start uploading Feather vs. Itsuki stuff here, starting with the first part that inspired the writing of Chapter 9 of Fish Scales.

NOTES:
I will be reuploading these images with the same descriptions as their FurAffinity counterparts, though I may add slight blurbs here or there with some extra info surrounding each part.
Also, I'm going to be changing this title image with each new transformation part uploaded. But regardless, whether they're ahead of the current point on Weasyl or behind, you can find the other versions of this image here!
