Good to hear! Bob the skull and Toot-Toot the faerie are the standout supporting characters for me so far. For some reason, the potion-brewing scenes are my favourite moments, and the moments much later in each book when he drinks the potions. Probably an odd pick, but it's among the more concrete descriptions of how magic works in the universe, and very creative. Plus, Bob is involved. Are the graphic novels good? As you can probably tell, I'm very into comics. Are they original stories, or comic versions of the books?
The graphic novels are mostly unique stories that get referenced either directly or obliquely in the novels, i enjoy them a lot. I think a few of them are re-tellings of parts of the books, and Storm Front might be a full length graphic novel somewhere. There's also short stories that have been published in some major anthologies that are plot relevant AND a companion mini-trilogy of short stories called "Working for Bigfoot" that are great world building and color on top of being hilarious. Toot Toot and Bob are great fun and are some of my favorites and the Fandom favorites in general. In an interview when Jim was asked about the inspiration for Bob he says that he was directly a insult to a former writing teacher who said you can't have a character just be a talking head who delivers exposition. So Jim made a talking head that mostly delivers exposition and ribald remarks.
