From Webkinz Insider Wiki
Get the frog to his treehouse at the end of each level. Hop on the lily padz and rocks along the way, but don't stand on a lily pad too long or it will sink underneath you. Make sure your energy bar does not decrease all the way; prevent this by jumping up and grabbing bugs with your tongue. The bees will cause you to lose energy, so avoid them.
There is a total of five levels of the game to complete.
You earn 1 Kinzcash for every 50 points you earn.
Use the arrow keys and spacebar to control the frog. The right arrow key makes you move one spot forward. Press the spacebar to jump farther, holding it in until the power bar reaches the desired strength. While holding the spacebar, use the arrow keys to change direction, and release the bar to jump.
Press the up arrow key to jump up and grab flying bugs.
There is no trophy available for this game.
To get maxium Kinz Cash, if there is a collection of three lily pads or rocks, try using the space bar to jump to the next space. This gives you a 25 point bonus.
