Nick Jr.com Description
Everest is a fun-loving Husky pup and the newest member of the PAW Patrol. She lives with Jake on his snowy mountain and loves 'belly-bogganing', sliding down on her belly. Ice or snow, she's ready to go!
Everest is an enthusiastic, kind, and helpful pup who loves performing rescues. She is very good friends with Jake, whom she is very affectionate towards. Even before she joined the PAW Patrol, she enjoyed rescuing penguins. She went out of her way to help Jake when they first met, by quickly offering him shelter in her igloo, guiding him through the storm, and digging a makeshift shelter to warm him up. She admits that she felt rather lonely without anyone to talk to. She was overjoyed to stay with him.
Everest also loves to eat anything liver flavored, such as liver flavored pup treats, and liver itself.
She is shown to be quite hyperactive and playful. She is more tomboyish than Skye, and likes snow-related activities, as well as anything to do with nature. They're still good friends despite their differences.
Like all of the PAW Patrol pups, Everest has her own personalized pup-tag. Hers is bright teal, with a shape of an Evergreen tree symbol on it, due to her status as the snow rescue pup, a place with a lot of them trees. It is used to communicate with Ryder, the Lookout, and the other PAW Patrol pups. When in use, the pup-tag flashes its light. The pup-tag also has a special mechanism, which allows the PAW Patrol pups to make video calls to other PAW Patrol members. Her Mighty Pup tag has a massive snowflake on it.
Everest's pup-pack is equipped with her teal vest. It features a grappling hook and contains a foldable rocket-powered snowboard (the latter revealed in "Pups Save a Snowboard Competition").
