Some of Becky Dreistadt's poses for Toffee in "Moon the Undaunted" seem notably different from the aired episode, despite most of the art she posts being 1-for-1 what airs. Seems like they originally had him being more openly angry/emotional in reaction to the spell before changing it for the final episode for whatever reason.
Didn't want to make Moon's involvement with him more impressive than Star's? Thought it was out of character or didn't want him showing his hand too early? Who knows.
That episode seems to have noticeably shit animation in some parts (notice how many times there are errors with things switching from left to right, or characters in poses they shouldn't be in based on previous shots) so any changes may have been pretty last minute. There have been a few complaints that maybe Toffee should have reacted more there, and maybe what they didn't go with would've actually worked better than what we got.
