Pork Bellies and New Beginnings - S1.E10

The knights meet the Tree Elves in the wind realm and find that the Elves have had problems with the Pork Warriors. Eccentro has gained a lot of weight, so the Pork Warrior think that he is the great King Porky. Eccentro has the Pork Warrior attack the Tree Elves, but the knights combine with the Elves' king and defeat Eccentro. The knights then go to the fire realm and meet a monster summoner named Beginner. Beginner decides to help them out by summoning the Fire Giant, but she accidentally summons a Rex. The now-slim Eccentro takes control of Rex and attacks the knights, so they try to get to the Ogre Village. Beginner tries to summon a meteor to crush the Rex, but it accidentally hits the Ogre Village. Luckily, the Ogres attack the Rex, thinking that it summoned the meteor.
