You could play games based on some of the Webkinz arcade and Tournament Arena games. For Example:
Chef's Challenge- Make up some crazy names (like the names of Webkinz recipes) and put out a variety of "ingredients". Let the kids make up recipes and you could have a judging panel. Chef or team of chefs with the most points wins.
Webkinz Supermodels- Pull out those old "dress-up clothes" and let them have at it. Have a panel of judges rate their outfits and give out points accordingly.
Dogbeard's Bathtub Battle- Basically battleship. Divide the girls up into teams, set up a grid on two posterboards, number the squares. Have each team of girls place "boats" (construction paper or cardboard) on the grids and take turns calling out the numbers. First team to sink all the boats wins.
These are just a couple of ideas. Checkout some of the games in the arcade or ask your daughter what her favorite ones are.
