From the Super Mario Wiki
Watchful "I" is a downloadable microgame in WarioWare: D.I.Y. and WarioWare: D.I.Y. Showcase. It was released on September 2, 2009 in Japan, August 2, 2010 in North America, and September 3, 2010 in Europe.
At the start of the game, there is a park with nothing moving. There is a delay until something starts animating and the timer will not tick down right away. The player must wait for an object to start animating and tap that object. Flowers, a guy in boxer shorts, buildings, stars, a tree, a bench leg, fence, or bushes will animate. The scene has some randomly placed items too. Part of the background is inspired from the hills with eyes from Super Mario Bros..
