Trivia

 * Zak's beliefs about the Rabbids can be seen as a tongue-in-cheek reference to the plot Rayman Raving Rabbids 2 when the Rabbids invaded the Earth.
 * It can also be seen as ironic as the Rabbids are depicted as antagonistic alien invaders in the video games, yet are treated as the somewhat benign inhabitants of Earth (and possibly the Moon) in the TV series.
 * Because he and Alice share the same grandmother, it's possible they are cousins.
 * Zak's model was reused for three characters, the Minstrel who accompanies Sir Roland, Rooney, and a character who is simply known as Steve
