A short story including a goldfish, a paper airplane, and a bucket of gumballs (please help me!!)

One day I was walking home from school when a paper airplane hit my head! "Rude, who would do that?" I thought to myself. I noticed it was not just any paper airplane... It was a flier for some sort of magic fish the pet store was selling! "Magic?" I thought to myself, "Let's see what this is about."

I ran over to the pet store and saw the banner hanging up that said "Magic Goldfish for sale! Only $2.99!" I grabbed my money out of my pocket and bought the fish.

"What does this fish do?" I asked one of the employees.

"Here," the employee said, "Take this bucket of gumballs and they will act as water for the fish! It's like magic!"

When I got home, I put the fish in the bucket, and it... turned into a gumball? I decided to eat it, even though I felt sad eating my fishy friend. It was disgusting. I waisted my money and will never do that again.
