Wiglaf wins a contest that brings Sir Lancelot to the Dragon Slayers' Academy for a day, but when Wiglaf's friend Erica suspects that Lancelot is not who he claims to be, trouble ensues.

Wiglaf faces the double embarrassment of having his wacky parents visit Dragon Slayers' Academy on Parents Day and starring in the school play as the brave but small knight, Sir Tinybottom.

When a wizard's spell goes awry and turns Wiglaf and his friends, Angus and Eric, into dragons, they spend a few days at Dragon Slackers Academy--a school for dragons with bad attitudes. When Wiglaf and his pals from Dragon Slayers' Academy meet up with the wizard Zelnoc, all they ask is for a little magic to help them get through the Dark Forest fast. But unfortunately, Zelnoc's spells always end with an "Oops! Sorry about that!" So, yes, the boys...

Wiglaf and his friends are on a mission to rescue Worm, the dragon they have raised from an egg, and are surprised to learn that the captor is not a gang of dragon slayers, but rather a young giantess who wants to keep Worm as her house pet.

Wiglaf and his pig, Daisy, are spending a DSA holiday with Erica at the Royal Palace, but King Ken has come down with the pox and Queen Barb's great healer is a not-so-great wizard who leaves King Ken speaking Pig Latin.

Wiglaf may be a dragon slayer now, but he has no gold to show for it. Will he be able to survive a trip to the Cave of Doom, or marriage to a rich princess?
