An easy level with just one frog and one stork.
Grab flies or flowers for bonus points.
Storks lay eggs as well for 10 points.
A more difficult level: three frogs to control, slipperly lilies and lilies with holes that transport the frogs back.
Fat frogs can only be pushed around, they cannot be controlled directly.
Four frogs and two storks require a lot more thinking.
A mix of a complex level design with a fat frog thrown in.
