What plurals are spelt incorrectly and the correct spelling (plural)

Hi! 

As you probably know, plurals are the form of a word to describe multiple of that word. Hopefully that makes sense. The correct spellings of the words above are as follows:

1. Puppys is incorrect, it should be spelled "puppies"

2. Shelves is correct

3. Buses is correct

4. Tomatos is incorrect, it should be spelled "tomatoes"

5. Radios is correct

6. Gooses is incorrect, it should be spelled "geese"

7. Pianoes is incorrect, it should be spelled "pianos"

8. Bruises is correct

9. Sheeps is incorrect, it should be spelled "sheep"

10. Echoes is correct

11. Watches is correct

12. Leafs is incorrect, it should be spelled "leaves"

Hope this helps :)
