Ok this is my onomatopoeia from school.

Snacking at the Horror Show

Drip Drop. The sink valve was leaking.
Creak. And the bottom step creaking.

I stopped in the middle of the room,
Drinking in all of its gloom.

It was silent when all of a sudden I hear
BAM from above, the sound was remarkably clear.

Thud as I move all the chairs.
Thump thump as I run up the stairs.

I come to a stop.
Phew, I have reached the top.

Screech. Great, another strange sound
Squish, I begin to look around.

Slurp, my friend is drinking a coke,
Crunch, and eating popcorn, he better not choke.

Shush, I ask for their noise to cut back
Howl, in the movie the werewolf is about to attack!
