Your original sentences are very good! Here's a corrected version with some small improvements for grammar and clarity:
Original: The savannah has striped zebras, pink flamingoes, and huge elephants. Elephants spray water from their trunk.
Corrected: The savannah has striped zebras, pink flamingos, and huge elephants. Elephants spray water from their trunks.
Explanation:
- Flamingoes should be spelled flamingos, which is the more common spelling.
- Trunk should be plural (trunks) because we are talking about more than one elephant, so each has its own trunk.
So, the fixed sentences are: The savannah has striped zebras, pink flamingos, and huge elephants. Elephants spray water from their trunks.
