The costume's original coin price was 1,000, but the game makers changed it to 1 coin to help all players unlock it faster. Unlike other costumes that are available in all countries, it was never changed to 10 coins price.
In Russian, Tzarevna (Царевна) means "Princess".
Tzarevna (along with Bogatyr) is only available in Russia.
The costume's original power (in the jelly lab versions) was extended time for all Power-Ups at the AVL.
Soccer Fan and Worker have the same powers as Tzarevna, only better and the power-up lasts much longer.
Apart from special offers in the top banners of the Shop, this costume as well as Bogatyr have never been found in any of the available or time-limited pods or through missions and events, making it extremely hard to upgrade. Most players who have the costume had bought it in jelly lab versions and were offered the costume cards required to upgrade up till level 5.
It was first released in 2.1.1 version on September 16, 2014. It cost $19,99 and was available in Russia for time-limited periods, usually in November. However, it was later found via a glitch at the price of 2,200 tokens, which is how most non-Russian players were able to buy it. Its upgrades required bananas and tokens and the max level of upgrade was 5. After the 5-Year Celebration Update, the maximum number of costume cards that were offered upon the conversion were 410.
