There's teleportation technology (the badges). Compared to that, cannons are easy.

Celes, who was busy trying to find the right way, did not see the wailmer arrive and hit her. In quick counter, she used swift attack, damaging the wailmer a bit before seeing the thing going and getting in for another rollout attack. Celes, in a quick movement, used a rock from bellow and propulsed herself up and above the wailmer, landing on him. She then used hidden power, striking the thing hard before it turned around and used water gun on her, making her get pushed back into the air a couple of feets. She then saw the thing going for a rollout attack again, before she uses confuse ray and then spins to the side, dodgng the attack as the wailmer keeps going up towards the surface, confused. Celes breath deeply, befroe letting out a hidden power attack,striking the poor wailmer hard with a critical strike, not fainting ir but close to it. Celes bresth deeply, before opening her bag and going and getting a slight drink of her soup, shaking her head quickly, regaining her senses, only to see a slight part of black and white of her costume showing. She quickly hides it, and then sees the wailmer do one more rollout attack at her, striking her back, befoee she uses shift attack, finishing the thing off, but making her feel slightly damaged. That fight took a bit out of her.
