With Super Mario Run heading to iPhones and iPads in just a few days, Nintendo’s Shigeru Miyamoto has been popping up all over, doing interviews and making appearances. Two new videos have surfaced, featuring Miyamoto showing off a variety of skills, including eating cake with one hand while playing Super Mario Run in the other. You can watch it below.

Additionally, while backstage on the Tonight Show with Jimmy Fallon, Miyamoto played a game in which he would guess the sizes of various objects, including a lightsaber, a “?” Block, a pizza, and more. Miyamoto says he attributes this ability to the fact that he would estimate the measurements of things while he was building a house. You can see how well he does with his guessing in the following video.

Super Mario Run will release for iOS devices on December 15th and for Android sometime in 2017.
