Nicole's pet arctic fox Roxy is known to be very good at navigating mines and tunnels, but in the episode of her debut, got lost in the tunnels, so Aphmau found her and brought her back to Nicole. She has the nickname bestowed on her by Aphmau 'Roxy the Foxy' and has a high-pitched squeak.
As of Season 2, her status is unknown but she had probably passed of old age.
Roxy has white fur speckled with light gray and black eyes.
Roxy is very quiet and cautious, yet still playful. Arctic foxes are apparently very good at navigating tunnels, so it is presumed that Roxy has that skill as well.
