Are these similes or metaphors
1. the road was a curvy as snake.
2.my mom told me that my room is like a pigsty.
3. mike is like a scared kitten as he enters the haunted house.

Just so you know...

A simile is comparing something with something else using 'like' or 'as' (for example - I swam in the sea like a fish or my room is like a tip). 

A metaphor is a word or phrase that compares something with something else (for example - his heart is metal or my room is a tip). Hope this makes sense!

1. The road was as curvy as a snake - Simile 

2. My mum told me that my room is like a pigsty - Simile

3. Mike is like a scared kitten as he enters the haunted house - Simile

Hope I helped!

Ifound this on google “use commas to separate two or more coordinate adjectives that describe the same noun. be sure never to add an extra comma between the final adjective and the noun itself or to use commas with non-coordinate adjectives.” i hope this you for what your looking for
