Construction
The construction of this tower is deadly and hard. The engineers, Phineas and Ferb, the architect, Dill "Fatboy" Anshar, and the supervisors, Isabella and The Fireside Girls, took part on the construction and had near-death experiences.
 * Phineas: He was climbing to the 155th floor of the building to run some utility installation one day when the helicopter crashes on a bird. The helicopter made it back to save ground before it obliterates. Phineas jumps out of the helicopter when it was near the ground and lands on a haystack.
 * Ferb: He was going down the first elevator installed that leads right to the 100th floor of the building. The elevator was new and final checks on the machinery is not yet done. When he reached the 67th floor, the cable went loose and sent the elevator down, plunging. But the brakes manages to stop it right before it hits the ground.
 * Isabella: She was closing down hes supervising activity when a storm hits the building. Some parts of the building that is not yet finished hits Isabella and traps her. Phineas went to the rescue. She suffers minor injuries and returns back to the site shortly
 * Dill: He was putting finishing touches on the bridge part of the mall, and suddenly the floor below came loose and formed a hole. He splashed into the river and luckily a ferry that almost shred him came to a full stop and helped him out of the water.
