There's a game called Duck Life. It's amazing. You raise a duck to become a racing duck and become the champion duck. Mini-games are training your duck to fly faster, swim faster, and run faster, all to win races that gives you money to feed your duck normal seed which increases it's energy or super seed which upgrades all of your ducks skills.
DISCLAIMER: I do not own Duck Life or any of the series. This is simply a blog post and I'm not looking for a lawsuit.
