I got the inspiration from some Yoshi's Island remixes I found on the nets.

Yoshi is, by far, my most favorite Mario character! List of faves by most favorable

Yoshi
The Koopas (the little turtle guys)
The Toads
Daisy

I drew this without a source or reference and it took me a few tries to get it right. Even so, the result may be questionable.

Drew the one on the top left first, the right second, and the bottom is the achievement.

I might go back and color the bottom Yoshi. Yeah.... Orange.
