Perfect for you if...
- You love graphic novels with silly humour and colourful illustrations that don't talk down to kids.
- You've read Dog Man or Hilo and want the next series to keep your child laughing through entire chapters.
- You appreciate puns, goofy characters, and stories that move at breakneck pace without getting boring.
Maybe not for you if...
- You prefer realistic or serious graphic novels with minimal toilet humour and bathroom jokes.
- You're looking for a book that teaches lessons or has a heavy emotional arc rather than pure fun.
- You want complex plots or mystery stories that require careful deduction rather than comedic chaos.
