Fish & Game
From the Super Mario Wiki
Fish & Game is a downloadable microgame in WarioWare: D.I.Y. and WarioWare: D.I.Y. Showcase. It was released on November 18, 2009 in Japan, October 18, 2010 in North America, and November 19, 2010 in Europe.
At the start of the game, two fish (presumably piranhas or Nibbles) need to be fed a piece of meat. Tap the meat to toss it. The arrow will guide where the meat will be thrown. Winning the game means both fish are fed.
