  • The spell is on page 149 with extended notes on page 150.
  • The spell does not require all elements. Some elements that are not required are WaterWind, and Time.[3] While Chen refers to having "Every Elemental Power," he is a liar and a criminal so his statements should not be taken as fact.[4]
  • For some reason, the spell's effects wore off when Garmadon and Chen were banished in "The Corridor of Elders," explaining why the two appeared in their human forms again in "Curseworld, Part II."[5]
    • The spell also wore off from Skylor in the former episode, though the reason for this is unknown.
    • Eyezor and Zugu reappeared in their Anacondrai forms in "Day of the Departed" even though Chen remained in his human form. However, this has nothing to do with the transformation spell and is presumably a result of their unseen Hall of Sidekicks statues depicting them in Anacondrai forms.
