Poochy is a dog that appears in Yoshi games. Poochy is spotted with a long and thick red tongue and duck lips. He has a red ball at the end of his tail, similar to a poodle. He barks constantly while he walks. He also has a great sense of smell, despite having no visible nose. Poochy has only been playable in Tetris Attack.
 Yoshi series
 Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3
Yoshi and company can ride Poochy in Super Mario World 2: Yoshi's Island. He can run at high speeds on yellow spikes, lava and many other hazardous forms of terrain and can also run over any enemies in his path. To ride Poochy, the player must jump on his head and look in the direction he or she wants to go. If Poochy hits a wall, he'll try to jump over it, which can give the Yoshi a boost. Sometimes, there will be a small gap that Poochy will run through, though unfortunately, the gap will be too small for the Yoshi. Ever faithful, Poochy will follow the Yoshi anywhere he goes except through a pipe or door. He can also swim through water while carrying Yoshi. To distract him, the player can throw an egg at his head. He'll play with it and won't pay attention to anything else.
Poochy first appeared in World 1's extra level "Poochy Ain't Stupid", where he's required to get across many fiery stretches of cave and was seen again in World 2-1's "Visit Koopa and Para-Koopa". He can also be found in "Jungle Rhythm...".
 Tetris Attack
Poochy also appears in Tetris Attack, allied with a Grinder. He appears as a character that Yoshi must initially beat in a one-on-one match of the game's panel-flipping puzzles, due to Bowser's and Kamek's magic spell, that made him work for them. After Yoshi beats him, the player can select to play as Poochy, though the difference ultimately amounts to cheerful barks as opposed to Yoshi's mutterings. Poochy replaces the earth fairy Thiana from Panel de Pon, the Japanese title that Nintendo remade to create Tetris Attack.
 Yoshi's Story
Poochy also aided the Yoshi clan in several levels of Yoshi's Story. Although the Baby Yoshis could not ride on top of him like before, Poochy did help the Yoshis find hidden fruit, allowing the baby dinosaurs to restore happiness to Yoshi's Island during their quest for the Super Happy Tree. In the levels he appears in, Poochy was normally chained to a post that needed to be pounded into the ground, thus breaking the chain and freeing Poochy. After being released, Poochy would run through the level and sniff out hidden items, most notably the Yoshi's favorite fruit - the melon. When Poochy discovers a secret hidden in the ground, he would stand by the spot and bark to alert the Baby Yoshi's attention. Poochy would wait until the Yoshi approached the spot, and would then move on to sniff out more secrets.
 Club Nintendo
Poochy makes a cameo in the Club Nintendo comic Rummelplatzquatsch. He appears on the screen of Mario's Game Boy which he bought from a fortune-teller. The Game Boy Camera included with the console is able to foresee the future. After depicting Poochy, a herd of dogs comes running towards Luigi, all peeing at him.
