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.

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.

When Mordred announces a three-day weekend for DSA, Wiglaf and his friends (including his Pig Latin–speaking pig, Daisy) are off to Erica’s castle. But when they arrive, they discover that Erica’s father, King Ken, has come down with a horrible case of liver pox. The wizard Zelnoc manages to cure the king’s pox, but as with all the wizard’s spells, there’s a magical mishap. Now, King Ken can only speak in Pig Latin! Can Zelnoc fix his mistake, or is there a better chance that pigs will fly?

After the witch, Morgana le Fay, puts a curse on Sir Lancelot, three knights-in-training from the Dragon Slayers' Academy set out to save him.

Wiglaf is off to Dragon Slayers' Academy and in for a first day of school he will never forget.

Wiglaf joins the other students of Dragon Slayers' Academy in searching the Dark Forest for the Cave of Doom, which supposedly contains the gold of the dead dragon Seetha.

While Headmaster Mordred is trying to impress a new student, the ghost of one of the school's founders besieges the halls seeking his stolen gold.

When the headmaster of the Dragon Slayers' Academy hears that Princess Belcheena will pay the matchmaker who finds her a husband, he decides that Wiglaf is the perfect candidate.

Wiglaf and his friends Angus and Erica find themselves teamed with the obnoxious Bragwort to represent the Dragon Slayers' Academy in an unevenly matched contest at the All-Schools Brain-Power Tournament.
