Nikoniko Mario

Nikoniko Mario (ニコニコ マリオ, Smiley Mario) is a transformation that appears only in chapter 8 of Super Mario-kun volume 2. In this form, Mario's head becomes big and so shiny that Bonus Coins beam from the head.

While fighting a Jumping Pumpkin Plant, Mario falls on Yoshi, who pops out an egg with a Yoshi Cloud inside. Mario jumps on the cloud and eats the Bonus Coins produced, becoming the big-headed Nikoniko Mario. Scared, the Jumping Pumpkin Plant runs away, hiding behind the panels. Mario's transformation lasts long enough for Luigi and Yoshi to take advantage of the shadow Mario's head casts and rapair themselves from the hot sun.
