Nintendog

Nintendog is the name of any puppy character from Nintendo's Nintendogs game series. Nintendogs are named after their debut game, which in turn is a portmanteau of "Nintendo" and "dog." Nintendogs have appeared in a few games related to the Mario franchise.

Nintendogs appeared in the microgame Nintendogs in WarioWare: Smooth Moves where the player has to high-five the puppies. They also appear in a similarly-named microgame in WarioWare Gold where the player must rub them.

A white Labrador Nintendog became an Assist Trophy in Super Smash Bros. Brawl. When it is activated it will distract the players by covering most of the screen and start clawing and barking, although it only worked on actual players. Nintendogs also appear as Stickers and a trophy.

In Super Smash Bros. for Nintendo 3DS / Wii U, the Nintendog returns as an Assist Trophy, though in this game it is a French Bulldog. A number of Nintendogs also appear on the Living Room stage in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. Ultimate.

Similarly, there are many Mario references in the Nintendog series. The player can find hats which are the same as Mario's and Luigi's, as well as various toys. These include Mario, Princess Peach and Bowser karts (designed with their Mario Kart DS kart style), which can be driven around the room, as well as Mushroom and ? Block toys to throw around. Additionally, the music played while driving the toy karts are heard from courses in Mario Kart: Double Dash!!.
