"Hello, Yoshi!" Are you ready to play? With this free application from the little-kid-friendly My Mario brand, you and your kiddo can play with Yoshi's face and delight in all his various expressions. ■Make Silly Faces Team up with your kiddo to see how silly Yoshi 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 Yoshi. ■Peekaboo! Invite Yoshi to play peekaboo by tapping on the leftmost icon in the ? Block menu. Boo may even make a guest appearance! ■Built-In Breaks Good night, Yoshi! Yoshi gets tuckered out after playing for a while and will fall fast asleep. At that point no amount of poking can wake him up! This is a great opportunity to take a break and help parents limit their child's screen time. If you want to keep the fun going, you can turn off this feature by tapping the gear icon in the top-right corner of the screen when the application starts. ■Play Offline There's no need to be connected to the internet to play this application. After you download it, you're good to go! Operation is not guaranteed for all devices that meet the operating conditions. It may not work properly depending on the device's performance and specifications, device-specific application usage conditions, etc. Please be sure to read the Health & Safety information provided in the application settings before you start playing. Settings can be accessed by tapping the gear icon in the top-right corner of the screen when the application starts to access the menu. ©Nintendo
