Chapter 11
Back on the submarine, Heinz had trapped Agent P in a corner.
"You have nowhere to run, Perry the Platypus!" Heinz exclaimed with a smirk. He also pressed the button to his Tidal-wave-generator-inator.
"The Tidal-Wave-Generator-inator is now warming up and ready to fire! And there's no way of stopping it now!" he proclaimed as he heard the -inator warming up on the top of the submarine.
Agent P smirked and jumped up. He punched Doofenshmirtz in the face and somersaulted to the steering wheel. He pushed it as hard as he could.
The steering wheel spun around and around, messing up the coordinates of the Tidal-Wave-Generator-inator.
Doofenshmirtz tried to stop the spinning but his nose was slapped by the steering wheel.
"What the Drusselsteinian Goozim?" Doofenshmirtz shouted, rubbing his nose, "Perry the Platypus! You know that I get..."
His face then turned green and nauseated.
"...seasick..."
Heinz took out a paper bag and barfed it.
Agent P rolled his eyes and stopped the steering wheel and locked it so that Heinz couldn't steer it. He then kicked Doofenshmirtz, sending him flying into the control panel of the Tidal-Wave-Generator-inator.
Heinz's backside landed on the fire button and his hand on another button.
He looked up at the coordinates and muttered, "I don't remember setting the coordinates for northeast...the sandcastle competiton is supposed to be northeast!"
The Tidal-Wave-Generator-inator fired once into the gulf, forming a giant 16-story tidal wave.
The button his hand pressed on was, not surprisingly, the self-destruct button.
Alarms began to blare all over the submarine.
10 seconds to self-destruct sequence.
Agent P spotted an escape hatch and jumped into the gulf and swam as fast as he could, leaving Heinz behind in the self-destructing submarine.
"I reeeeeally gotta stop putting self-destruct buttons on my machines..." Doofenshmirtz muttered before the submarine exploded, along with the Tidal-Wave-Generator-inator, sending the doctor up in the air.
"AAAAAIIIIIGGGGGGHHHHHHHHHHH! CURSE YOU, PERRY THE PLATYPUS!"
At the sandcastle, Phineas, Ferb, Isabella, and a couple of the Fireside Girls were relaxing on the lazy river. Phineas was on an inflatable device, sipping on lemonade.
"Ah...this is the life! Ferb, cross off one giant sandcastle off the list!"
Ferb rolled out their list of Big Ideas on a piece of paper and crossed off 'giant sandcastle' with a No. 2 pencil.
"The only thing that would make this day more complete is riding a giant tidal wave on our custom-make rocket-powered surfboards!"
He pointed to his orange-colored surfboard for all of his other friends to see.
"But there's one problem, Phineas..." Isabella said, looking at her surfboard, "Where are we going to find a giant tidal wave in the middle of the gulf?"
"I guess we'll have to wait for one, Isabella!" Phineas replied.
Outside the sandcastle, Gretchen stood at the lookout tower and spotted something unusual in the distance. The unusal thing, though, was growing bigger and headed towards the island.
"Guys...we got a tidal wave coming!" she blurted out on the PA system that they installed throughout the castle.
When Phineas heard this message, he and his friends jumped out of the lazy river and got their surfboards with small rockets underneath them.
"Gang! Ready?" Phineas shouted, putting on his helmet.
"We're ready!" his friends yelled. They too put on their helmets.
"Okay, turn on your rockets by pressing your foot on the pedal!"
Phineas and his friends pressed the gas pedal, activating the rockets. He pressed a blue button on a remote control as a sunroof made entirely of sand opened up to the sky.
"Let's liftoff!" he proclaimed as they took off on their rocket-powered surfboards, one by one, from the floor. They went through the roof as the giant tidal wave crashed into the sandcastle, taking it to the sea.
Phineas and his friends, meanwhile, were all surfing on that tidal wave in a circle.
"This is so cool!" he proclaimed. The wave then dissipated as Phineas and the rest landed safely on the sand, standing upright and holding their surfboards in their hand. The rockets then folded up neatly into the board.

A few minutes earlier, Candace continued to speed the boat up while Bonnie was holding up a giant map.
"According to the map, Candace, we'll approach the island where your brothers are at in a few minutes! We'll show them the sandcastle!" the brunette said
"And finally, my brothers will be busted once and for all!" Candace said, determined that the sandcastle was going to slip away from her this time.
_
"What has gotten into my little Bon-Bon?" Veronica asked Linda.
"Let me ask you this, Ms. Rockwaller. Has she been with Candace all day long?" Linda proposed this question.
"You mean the one with the tall neck?" Veronica questioned.
"Yep, that's her." Linda replied, pointing to her daugher.
"Rest assured, Mom!" Bonnie proclaimed, "You will see what Phineas and Ferb have done and you will bust them on the spot!"
"There's your answer right there..." Linda sighed.
"Now how do you fold up this thing?" Bonnie asked. This was the first time that she was trying to fold up a map.
"I can't get to it right now, Bonnie! Remember? Two hands on the steering wheel?" Candace reminded her.
"Let's see, if I tried to fold it here..." Bonnie began, trying to fold up the giant map, but then a gust of wind blew it out of her hands and into Veronica's and Linda's faces, covering their eyes.
"I can't see!" Veronica complained.
"Get this map out of my way!" Linda whined.
The speedboat landed on the sand. Candace and Bonnie gasped in wonder at the sandcastle!
"I can't believe it! It's still there!"
The girls then turned to their moms for a moment, their eyes closed.
"Allow us to present to you..." Candace began her sentence.
Bonnie then finished it off "...a giant sandcastle by Phineas and Ferb!"
Linda and Veronica removed the giant map from their faces.
"And I see...nothing..." Linda remarked.
Both Bonnie and Candace opened their eyes and gasped. Not only was the giant sandcastle gone but there was Phineas and his friends standing there on the sand, surfboards in their hands.
"What?!" Bonnie gasped in shock in horror. Candace, meanwhile, was not amused. She had seen this process before.
"Hi, Mom!" Phineas shouted, waving to his mom.
"Oh, hello, Phineas! Did you and the kids enjoy your time on the Kids' Island?" Linda asked.
"Of course! We built a sandcastle for Bonnie!" Phineas said.
"A sandcastle? Oh how imaginative!" Linda replied in wonder and amazement.
"Wha..." Bonnie stood there, slack-jawed in amazement, "This is not possible! The sandcastle was right there! It was RIGHT THERE!"
"Welcome to my world, Bonnie." Candace snarked.
Veronica came to her daughter's side and said, "Bon-Bon, I think you've sent too much time in the sun!"
"But...but...but...!" Bonnie whimpered, stunned in silence of how a 15-story sandcastle disappeared in the blink of an eye.
"Come on, kids! We're heading on back to shore!" Linda insisted.
"Right with ya, Mom!" Phineas said as he and his friends boarded the boat.
"If you don't mind, Candace, I will take the helm of the boat." Linda said, taking the helm of the boat.
Candace sighed in disappointment, another busting attempt failed, "Fine, Mom..."
Linda sped up the boat back to shore.
