Sound blocks, available tools and Amiibo confirmation

Nintendo has released a video showing off Super Mario Maker, including some features that have been unannounced.
Among the tools announced were a frog that can trigger sound and graphical effects, and the GamePad's microphone can be used to record new effects (such as "Happy birthday"). Shaking a music block in the editor will create a music block that plays a different pitch depending on its screen height, allowing for rudimentary music creation.
The trailer also reveals that a limited set of tools will be available on the first day the game played, with spending five minutes in the editor unlocking more items the next day.
The final part of the trailer confirms that every Amiibo except for the Mii Fighters will be usable in the game during the 8-bit mode.
