One player is chosen as the captain. Anybody without a partner is out. One partner must lay on their stomach while the other places their foot on their partner's back. Children without a partner or pairs that are too slow are eliminated.
Every player falls on their back and sticks one leg in the air.
The last ones are eliminated. The last player to the base is eliminated. The lightest player rides on their partner's back. Those without partners or who assemble the crow's nest too slowly are eliminated. Children form groups of three and sit in a vertical row.
