The plot of Jocko, or the Monkey from Brazil, a worldwide hit, provided an opportunity to bedazzle the audiences of the time with skilfully rendered behaviours of a domesticated monkey. The non-speaking part of Jocko, played in a mask and a spectacular costume, required extraordinary physical fitness and pantomime skills to perform. In Lublin, Stanisław Krzesiński excelled as Jocko. He wrote about the play thus:
At the back of the stage, the ship in full view, with the sails and the masts, with people on board, fighting the storm. The ship sailed onto centre-stage and then hit a rock, only then crashing and sinking. The masts tumbling down, the ship falling to pieces, people drowning, a child falling in the water and then rescued by the ape, all made for a spectacular effect.
