A character design/idea I thought of last night and had to (sloppily) doodle in paint. Really I am more proud of the idea and design rather than worried about picture quality, haha.
Spookmark: It's a cat-like bookmark ghost. Not so much a ghost of any living thing, but more of a apparition resulting from the bookmarked place held in someone's book, unfinished, before they died. It is always searching for the spirit of it's reader to finish the book. It only speaks in unfinished sentences. Very friendly, but don't entrust it to get something finished!
(I say "it" because it has no gender, being a ghost of an idea/situation/object)
