They were just having some fun!
Here how your kids can have some "penguin style" fun playing this toastier indoor version of this Arctic game:
- Lay a trail of pillow "ice floes" about 2 feet apart on a cleared, carpeted floor
- Have everyone line up single file (this is how penguins migrate north)
- Take turns hopping from pillow to pillow
The "penguins" must land with both feet on each "ice floe"; if they don't, they are considered to have fallen in the drink and must step aside.
Space the pillows farther apart for each new round until all but one "penguin", the winner, has been eliminated.
