Grammar correction for a 6-year-old: 'You can enter the platypus’s burrow from the ground and underwater'

Correct sentence: You can enter a platypus's burrow from the land or from the water.

Why?

1. The original sentence used "and," which makes it sound like you enter the burrow both from the ground and from underwater at the same time. That is confusing.
2. Using "or" shows that you can enter the burrow either from the land or from the water (one or the other).

Other short versions:

• You can enter a platypus's burrow on land or underwater.
• You can enter a platypus's burrow from the ground or from the water.

Fun fact: Platypuses live in rivers and sometimes go onto the riverbank, so both ways are possible, but not at the same time.
