Mark the two banks of a river on the floor.
Split the group in half. One half goes to each side of the river.
One scout is the crocodile in the river.
Number off all people on each team.
The crocodile calls out a number and the scout from each team with that number must run to the far bank without being tagged.
If the crocodile tags someone, he switches places with him.
If a scout does not leave his bank before the other running scout reaches his bank, then he switches places with the crocodile. This is to keep the game moving.
No scoring, just for fun.
