Sphenishchev is a penguin in the Gower Quest with the ability to not be remembered. He used to be a penguin spy who used his non-notability to gather data, until the day his non-notability backfired and he was continuously spotted by those who had forgotten that they had spotted him. Due to this incident, he was fired and relegated to Behind the Scenes as removed content.
During the Gower Quest, he is recruited by the adventurer to break into the nearby bank, using the skills he picked up as a spy to guide the adventurer through breaking into a safe deposit box. He gets irritated by the adventurer constantly forgetting who he is and remarks that the player knows who he is.
- His name is a reference to Sphenisciformes, the order to which all penguins belong, and the former Premier of the Soviet Union Nikita Khrushchev.
- His ability is a reference to the 2009 Penguin Hide and Seek glitch, which allowed players to spot the same penguin over and over again for unlimited penguin points.
