Alien Ambush

Alien Ambush is a microgame in the Sci-Fi folder in WarioWare, Inc.: Mega Microgame$!.

Gameplay
There is a cage on the left side of the screen, and an octopus-like alien walking toward it from the right. The player must press the "A" button with good timing to drop the bars on the cage and trap the alien. The player may drop the bars on the alien as well. Depending on where they hit the alien, it will either be pushed inside or pushed out. On level one, the alien just walks straight through. On level two, the alien may pause or jump before walking through. On level three, the alien will pause shortly after starting, then roll into a ball and roll through the cage at two times its normal speed.
