Is there any way to figure out which of these are graphic novels/graphic comics? DS6 and DS4 are on a graphic novel kick right now (we're reading to them), and we're tearing through the ones I know pretty fast! I'm running out of titles that are age-appropriate, especially for DS4!

We've been reading the Zita the Space Girl, Baby Mouse, Squish, Lego Ninjago, Bird and Squirrel, Super Agent Jon Le Bon, Guinea Pig Pet Shop Private Eye, Mr. Pants, Binky the Space Cat, Tiny Titans and Scooby Doo Team Up.
