The trailer for the game incorrectly refers to platypuses as duck bills and seals as sea bears. It's possible though that this could be a translation error. The game's developer BrainGame is based in Germany, where platypuses and seals are referred to as schnabeltier ("billed animal") and seebär ("sea bear") respectively. These were two of the earliest names given to platypuses and fur seals when they were discovered by humans.
