The protests in Russia began after Alexei Navalny published the so-called palace film.
The film shows what Navalny claims is President Putin's castle-like building on the Black Sea of 18,000 square meters.
It includes an underground hockey rink, striptease stage and the so-called aqua disco, a room with a pool and a fountain.
The Russian comedian Andrei Gudkov has quickly made a song called Akvadiskoteka in which he dismisses corruption and extravagance, a song that quickly went viral.
The song is now being used as a kind of verbal bat by Russian protesters in their protests against Putin.
In the clip above, protesters are heard singing Andrei Gudkov's song during the protests in Moscow.
