After Danny Dragonbreath's best friend Wendell the iguana is bitten by one of the hot dogs from his school lunch, he starts to turn turn into a were-wiener.

Danny Dragonbreath is excited about going to camp with his best friend Wendell and classmate Christiana even though his obnoxious, seven-year-old cousin Spencer is going too, but things change when Spencer finds a real jackalope.

When Suki the salamander--the new foreign exchange student--is being stalked by ninja frogs, Danny, Wendell the iguana, and Suki travel to Great-grandfather Dragonbreath's home in mythical Japan to find a solution for the problem.

"Danny Dragonbreath must save his cousin from the ultimate enemy: Knights!"--

"Danny Dragonbreath travels to the farthest North to find a way to relight his fire before it's too late"--

"Harriet Hamsterbone sets out to reverse the curse on twelve mice princesses who are forced to dance all night, every night"--

Never a conventional princess, Harriet becomes an adventurer after learning she is cursed to fall into a deep sleep on her twelfth birthday, but after two years of slaying ogres, cliff-diving, and more with her riding quail, Mumfrey, things go awry at home and she must seek a prince to set things right.
