Continuity: 1-6 A Gummi By Any Other Name: When Cavin climbs the wall of the prison tower, he accidentally dislodges a stone which falls onto the helmet of the ogre guard beneath. But in order to do so, it would have had to fall round a third of the tower's width, since Cavin is climbing out of the guard's sight.

Continuity: During most of this episode, Princess Calla wears ragged peasant's clothing. But in the instant where she uses the Changing Hat to transform into Igthorn, she wears her usual princess dress.

Continuity: When Cavin climbs the tower out of the sight of the ogre guard, a stone comes loose under his hands and falls on the guard's head. But in order to do so, it would have had to round about a quarter of the tower to come down on the head.

Plot hole: 1-6 "A Gummi By Any Other Name": The Changing Hat has the habit of tranforming its wearer at the mere mention of a name (or even a species type, as seen before when Sunni accidentally transforms into an ogre). However, when Calla impersonates Igthorn and faces off against him, she loudly says the name "Toadwart" and doesn't transform.
