1. Yoshi
Which finally leaves the best the last. There is one pet that has been with us all for as long as I can remember. Yoshi, the amazing little green dinosaur who has helped Mario and Luigi through all sorts of adventures through the ages. She makes the levels easier and gives us that extra few bumps into the bad guys, especially if you manage to jump back on her again after she starts to run away. She has provided us with extra lives and lots of entertainment. And don't forget that she loves to eat those bad guys clearing the way for a free run to the finish line.
