That's exactly what I mean. The Mind Flayer was there for three strips for a gag of the comic being taken down for copyright infringement, while Sunny is a major character who is intended to play a major part in the final book. That's why I believe the Giant was given an agreement by WotC to add a beholder as a major character, with maybe some restrictions to avoid making it seem like beholders are free use (not directly stating Sunny is one, the number of eyes difference, stuff like that).
