Nintendo unleashed a promotion for Mario Tennis Open some time ago whereby you'd have to travel to various supermarkets to obtain a code for special Yoshi characters. We lead you in the right direction a few times but in case you missed any of these you'll be glad to know that Nintendo have provided us with a video featuring all seven variations of Yoshi for you to scan into your 3DS. 

Each Yoshi boasts its own specific stats so don't go thinking this is merely a change of skin. For those extra hardcore Mario Tennis players, scroll below for a Metal Mario code and a Yoshi costume for your Mii, courtesy of Nintendo-Gamer. 

Are you still playing Mario Tennis Open? Will these colourful Yoshi lure you back into the game?
