Nintendog

A Nintendog is a puppy from the 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 series.

Nintendogs appeared in the microgame "Nintendogs" in WarioWare: Smooth Moves where the player has to high-five the puppies.

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.

A Nintendog of the Beagle breed can be seen in the background of a stage based on the Nintendogs game itself from Super Smash Bros. for Nintendo 3DS. Another Nintendog, a French Bulldog, will also return as an Assist Trophy.

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!!.
