Nerida and Victoria – these dwarves took their names from two steamboats that cruise the river Odra during summer. You can meet them on board these ships. As they are twins, they not only look the same, but are also both captains of their ships. They grip the helm tightly and keep the tourists from leaning over the side. They also like to sing, that’s why you can often hear the “captain tango” floating over the river waters.
