It's not easy for Danny Dragonbreath to be the sole mythical creature in a school for reptiles and amphibians -- especially because he can't breathe fire like other dragons (as the school bully loves to remind him). But having a unique family comes in handy sometimes, like when his sea-serpent cousin takes Danny and his best iguana friend on a mindboggling underwater tour, complete with vomiting sea cucumbers and giant squid. It sure beats reading the encyclopedia to research his ocean report . . .
