I am a large "Flipper" fan; definitely, yes, do continue!

Well it's an interesting start.

I am excited to see some Flipper fanfiction, too. I have wondered why there is NONE out there, when Sandy was such a heart throb in his day.

I hope we'll see some excitement! (Those "close calls" that they always had scream out "write me, write me!"

While your grammar could use a beta, I don't think it is enough to stop writing for. I'd like to see you finish this. Who knows? You might encourage others to write Flipper stories.

There's someone in the kitchen, Sandy." Bud said sitting down next to his big brother. (Needs comma, not period after Sandy.)

"What do you mean someone is in the kitchen of course Dads in the kitchen." Sandy replied shoving Bud off his bed as he pulled on a shirt. (New sentence - Of course Dad's in the kitchen," Sandy)

"Not just Pa, a girl." Bud urged on.

"A girl! Golly!" Sandy said as he and Bud walked into the kitchen. Walking in Sandy saw that Bud was right, a girl a little younger than him and a little older than Bud with long copper colored pigtails sprouting from the top of her head. (Run on sentence. Periods are your friends.) She was in a pair of jeans and a blue plaid button down shirt.

"Pa!" Bud said loudly.

"What is it Bud?" Asked Porter. (What is it, Bud?" asked Porter.)

"Whose she?" Bud asked bluntly. (Who is or Who's)

"I'm Sadie." The girl laughed. "I'm your sister, Bud."

"What!" Bud's jaw dropped.

"Bud when your mother died your grandmother told me I might be able to raise two boys, but without a woman I could never raise two sons and a daughter, so she took Sarah home with her to Texas." Porter explained. (Another run on.)

"I remember you!" Sandy exclaimed, looking at his little sister. "Your much taller, Sadie." (You're)

"I'd assume so. Last time you saw me I was three!" Sadie exclaimed, hugging her brother.

"Yeah that makes sense…" Sandy laughed.

Should I contine? (Continue)

(Only if you promise to use spell check and better grammar)

Yay! I was very excited to see Flipper fanfic! About time! You should definitely continue. But, try and describe things more. Instead of talk talk talk, try and get the reader to see what is going on. Slow things down a bit. Other than that, it's a great start!
