A mega yard Yoshi Amiibo is on it's way for Yoshi's Woolly World on Wii U.
Tapping the gamepad with giant Yoshi will activate 'Double Yoshi' into the game and allow you to save a Yoshi pattern directly to the Amiibo (the same as the smaller Amiibo Yoshi).
Costing $40 it's more than double the size and price of the standard Amiibo Yoshi.
