Blob & Key

Blob & Key is a downloadable microgame in WarioWare: D.I.Y. and WarioWare: D.I.Y. Showcase. It was released on March 17, 2010 in Japan, February 14, 2011 in North America and March 18, 2011 in Europe.

Gameplay
The objective of the game is to get the blob inside the lock. The shape of the lock is either a circle, an oval, or a cone. The blob will slowly transform into one of the three shapes, and the player must tap the screen to send it in when it is in the right shape. For the game to count it as a win, the blob must have finished transforming into the shape: if it is not fully transformed it still counts as a loss.
