Fin Fin is a virtual pet similar to Tamagotchi. The special feature of the simulation is speech recognition with a accompanying microphone. Of course it doesn't really understand what the player is saying but it reacts to the mode of speaking - a friendly tone makes it happy and loud or hectic speeches makes it sad. Sometimes it speaks back and a "conversation" occurs. Over time it learns to distinguish the player's voice from others. Like other virtual pets the Fin Fin needs to eat and sleep. The game is set in a virtual world where the Fin Fin can meet other animals (the player can't interact with those). The pet either plays with them or is scared which affects its mood. A happy Fin Fin rewards the player by singing a song or performing stunts.
