It's Tiny Wings Mania!!
Consider making a "Tiny Fins" that uses a flying fish instead of a bird! See how far you can fly without passing out from being out of the water too long. But be careful. If you fly over the city, you may have trouble finding water when you need it and just end up flopping on a sidewalk in downtown Manhattan.
Or, how about if you make a "Tiny Wings" that uses a kid's riding airplane toy instead of a bird? Because it's not a real plane, it can't achieve flight, yet the toy secretly longs to soar with the birds. So, your job is to push it all the way to the top of a really high mountain and then climb in it and ride it off a cliff! The object will be to see how far you can ride before before the plane smashes into the ground in a fireball.
