Climb the Clock Tower:

"Baroque Works?" a seedy-looking man repeated. He wore a cowboy hat and a jacket that read 'Baroque' and stood with a group of similarly dressed men while being questioned by a group of Marines. Meanwhile, the Rebel Army and the Royal Army continued to fight it out nearby. "I've never heard of such a company. Are you sure it exists? We're just ordinary citizens of Alabasta Mr. Marine. You wouldn't wanna hurt good citizens... just because there's a rebellion... would ya?"
SLISH! SLASH! The group of Baroque Works Billions fell to the ground and Tashigi stood over them with her sword extended.
"Wait! Sergeant Major!" one of the Marines protested, "They..."
"SHUT UP!" Tashigi interrupted. "Why were you hesitating, Marine? If you wait for proof you won't prevent anything! You should be able to tell who the enemy is immediately!"
"Yes, we're very sorry Sergeant," the Marine apologized while he and the others in the group all saluted Tashigi.
"We only have until four thirty," Tashigi thought to herself. "We're running out of time!" Tashigi looked towards the clock tower to check the time but found that one of the four faces had swung opened. She blinked in surprise. "The clock..." She adjusted her glasses and spotted the large cannon that was pointing out of the circular hole.

"Ribbitribbitribbit!" Ms. Father's Day laughed as she and Mr. 7 stood on the rim of the circular hole in front of the cannon. "Hey listen, Mr. 7, I think this is a very important mission that was assigned to us."
"I think you're absolutely correct about that, Ms. Father's Day," Mr. 7 agreed.
"And do you know what else?" Ms. Father's Day asked. "I bet we'll get big promotions for pulling this off successfully! Ribbitribbitribbit!"
"Ohahahahahaha!" Mr. 7 chuckled. "I do hope that is the planned reward! After all, this is quite a difficult mission when you think about it Ms. Father's Day. We're shooting a cannonball into the ground using such a big cannon! Ohahaha! So the reward should just as big! Ohahahahaha!"
The fools had no idea that the bomb they were about to fire would destroy everything in a three mile radius and that they were within a three mile radius of the explosion. They weren't going to be promoted for succeeding in their job, they were going to die in the explosion along with everyone else. Some reward.
The clock struck four twenty-nine, just sixty seconds left.
"Ribbit!" Ms. Father's Day called out. "It's almost time to go now Mr. 7!"
FSSSHH! Mr. 7 lit a match and held it up in front of him, "We're ready to fiiireeee!" he cheered.
Down below the two oblivious armies continued fighting. They had no clue that they'd all die in less than a minute if the Straw Hats didn't do anything to stop the two almost equally oblivious agents from lighting the cannon's fuse and firing the bomb into the square.

BAM! BAM! BAM! A cluster of Billions dropped to the ground just outside of the square courtesy of a hail of bullets from the one-armed Lieutenant Devo.
"RELOAD!" the Lieutenant ordered as he held his revolver to the side and snapped it opened. The used shells dropped to the ground while one of the Marines backing up the Lieutenant ran over and loaded another six bullets into Devo's revolver. Lieutenant Devo could still fire a gun with one hand but normally he would reload his own gun in fraction of the time it was taking the other Marine. Clearly, Devo's wound from Crocodile would always have a lasting impact.
