- Although the moon appears to be full, the Zebra brothers never use their Ghost Lanterns.
- Woo the Wise calls the octopus army "Octopi", which is incorrect, when the plural for octopus is "Octopodes".
- They also were erroneously referred to as "octopuses" at times.
- First time Jumpy Ghostface's swirly eyes and fantasy are shown.
- As a nod, the Zebra brother say the plural meaning for octopus wrong.
