When Sailor Moon uses the Spiral Heart Moon Sceptre, she calls the attack "Rainbow Moon Heart Attack", when it should have been "Moon Spiral Heart Attack".
Pegasus upgrades Sailor Moon and Sailor Mini Moon's powers, giving them new brooches, and thus a new transformation phrase (and they share the same transformation sequence), "Moon Cosmic Dream Action". Sailor Moon's scepter is also upgraded and she gains the attack "Moon Gorgeous Meditation". Sailor Mini Moon's scepter is transformed into the Crystal Bell, a bell that allows her to summon Pegasus.
This is the last time that Sailor Moon uses the Spiral Heart Moon Sceptre and Sailor Mini Moon uses her Pink Sugar Rod.
