Goof: When Wiz-Ra releases the ThunderCats from the spell, you can clearly hear Snarf's voice say, "I must have been asleep." However, Mumm-Ra never cast the spell on Snarf and he had been the one to help free the ThunderCats by getting the helmet to Wiz-Ra.
When Wiz-Ra, Cheetara, and Snarf infiltrated the Black Pyramid, Cheetara ran and pushed the Vulture King Statue so that it would look like the day was over. However, Mumm-Ra had only spoken about that to Slithe in private before they arrived, thus she should not have known about it.
Wiz-Ra's enchanted golden helmet of Fahd Niore has the power to control minds.
Mumm-Ra is able to monitor the passing of a day in his pyramid from a ray of sunlight which hits the right eye of the Vulture King statue and passes to the left eye where it signifes the end of the day.
Mumm-Ra turned a stone cat into flesh and blood. However, when it entered Cheetara's room, it vanished into Cheetara's body like a ghost.
This is the first episode in which we see a ThunderCat wearing clothes in bed.
Cheetara: Will I see you again, wizard?
Wiz-Ra: Only in your dreams, beautiful Cheetara. Only in your dreams.
Cheetarah: I'm glad it all turned out well, but maybe if I had trusted you more, and told you about Wiz-Ra, all this wouldn't have happened.
Lion-O: That's in the past, Cheetarah. But in the future, we must hold nothing back from each other, if we are going to remain a team. Right?
All: Right! Thundercats, Ho!
First Appearance: Wiz-Ra
Mumm-Ra and Wiz-Ra are shown fighting in a flashback. In the fight, a stray energy bolt destroys the nose of a large sphinx statue. This is supposed to explain the missing nose of the Great Sphinx of Giza, built by the Egyptian Pharaoh Khafre around 2570 B.C.
