With the underlying gameplay largely complete early in development, Miyamoto and team focused the majority of their efforts on graphics, audio and dialogue, and enemy AI, seeking to harness the new processing power provided by the Nintendo 64. For example, when developing the animation sequences for "Star Fox 64", the team worked to make the characters' mouths pop open and closed along with their audio. This reduced the amount of animation work put into the series and was inspired by the way puppets appear to talk, as Miyamoto was a fan of the British puppet-based show "Thunderbirds". The development team also realized that adding dynamic audio would enhance the 3D gameplay experience as the player's allies could audibly signal when the player was being pursued by an out-of-camera enemy unit. In writing dialogue for the game's characters, the developers sought to invoke more traditional historical dramas, adding more conventional lines such as "I've been waiting for you, Star Fox" and "You're becoming more like your father." Edgier dialogue such as "I guess it's your turn to be thankful." was written for the character Falco Lombardi, while more supportive dialogue such as "Never give up. Trust your instincts!" came from the character Peppy Hare.
