Here are four simple, two-words-shorter versions (good for a 5-year-old):
- Each camel foot has two toes that spread wide so it won’t sink in sand.
- Each camel foot has two toes that open wide so it doesn't sink in sand.
- Each camel foot has two toes that spread apart so it won’t sink in sand.
- Each camel foot has two toes which spread out so it doesn’t sink in sand.
Quick explanation: camels have two toes on each foot that spread like a fan so their feet don’t sink in the sand.
