The "Hello, Mario!" series is a collection of apps in the kid-friendly "My Mario" series.
In "Hello, Mario!," you can play around with Mario's face and enjoy all of the various expressions he has to offer.
■Make Silly Faces
Team up with your kiddo to see how silly Mario can get when you pull and stretch his face or take turns poking and spinning him around. Tap on the ? Block in the top-left corner of the screen and select an icon to make items—like a Super Mushroom, a Super Star, or pipes—and even enemies appear alongside Mario.
■Peekaboo!
Invite Mario to play peekaboo by tapping on the leftmost icon in the ? Block menu. Boo may even make a guest appearance!
