"Pink Moon Crystal Power, Make Up" is the command used by Chibiusa Tsukino in order to transform into the eternal form of Sailor Chibi Moon with the Pink Moon Crystal. This command was only used in the manga.
In Act 49, Chibiusa shouted the command phrase “Moon Crystal Power!” to give power to Eternal Sailor Moon’s Eternal Tiare. Afterward, she transformed into her Eternal uniform along with the other Sailor Senshi. This was the first time her Eternal form was seen.
