Beware! It's Friday the 13th: Dragon Slayer's Academy 13

Things couldn't be better for the greedy headmaster of DSA. Lasses are lining up to enroll in his school, and more students means more gold! But when The Medieval Times headline announces that the Bad Luck Dragon is on its way to DSA, Mordred orders his students to hunt for every good luck charm ever invented. But can a bunch of phony 4-leaf clovers help Wiglaf and his friends defeat the dragon Snagglefahng?...or will their luck run out?
