This plush dragon epattern by Scarlett Royal has a full video tutorial, It was made on the 3/8" 24 peg CinDWood loom, but any 24 peg loom will work. It is an intermediate advanced pattern.
I wasn't sure I'd like it once I unpacked it, cause it was bigger than any loom I have. But I'm loving it! Easy to maneuver, started using it the next day! Can't wait to make more blankets on it.
