Writers Note: hello this is my first fanfic so I expect some criticism, and if you are not familiar with ben 10 or gravity falls I recommend watching them for context.
It was the middle of the day in the Rust Bucket the Tennyson's were driving to a place called Gravity Falls
Gwen Tennyson sitting on a seat said "Grandpa we have already been to plenty of tourist traps"
Grandpa Max replied "I just have something to do"
"Let me guess this is about the plumbers or some artifact that makes you crazy" Ben Tennyson said barely awake
"What can I hide now" Grandpa Max said with a sigh
They would enter Gravity Falls
"Lame place for a plumber base" Ben Tennyson said
"Not a plumber base" Grandpa Max said
"Some high energy readings I picked up a few days ago I was going to go but you were on a mission to stop the watch from exploding" Max replied
They would go to the forest
Gwen Tennyson looked at a large lumberjack statue and said "this place is really creepy"
"Not as creepy as your witchcraft" Ben Tennyson laughed
"Cant wait until you turn into Stinkfly again" Gwen Tennyson said with a smirk
A couple of kids would run across the road there names being Dipper and Mabel
Grandpa Max with a hard stomp would press on the breaks
Then they would here loud stomps then the kids jumped out of the way then a T Rex ran in the way and the Rust Bucket hit the T Rex
Dipper and Mabel would look back in shock
"Are they ok?" Mable said
"There's no time to check!" Dipper said while running
Mabel stood in terror while the T Rex got up and turned to Mabel
A obscured person would fly out of the Rust Bucket making a hole in the roof with flames it was Heatblast and he shot multiple Fireballs at the T Rex
Dipper would hear the fire balls and look back
Dipper shouted "MABEL COME WITH ME"
Mabel would reply "I'm watching a hero"
Heatblast would land back on the ground and threw a fireball in the T Rexs mouth and it would stay still then Heatblast would float over with Flames and land near Mable then he would explode the ball
Heatblast said "No need to thank me"
Mabel said "You are hot"
Mabel regretted her statement and said "I MEAN COOL!"
Heatblast replied "I'm a million degrees what can I say?"
Gwen Tennyson would break down the door of the Rust Bucket with a magic blast and says "Hothead can you fix this and help Grandpa!"
Heatblast would say to Mabel "Well have to go"
Mable said "See you I guess" and she would walk to dipper
Dipper said "Mabel can you not get another crush"
Mabel said "That's a no"
