“Shotzo is an impregnable, projectile-spitting foe and one of Kirby's oldest and most commonly-occurring enemies, making its debut appearance in Kirby's Dream Land. They look like cannons made of black metal and attack by shooting cannon balls at Kirby. While most Shotzos are unable to move, they sometimes drop from the sky on Parasols. Regular Shotzos come in two variants: One that sternly keeps facing in one direction, and one that constantly adjusts its aim to hit Kirby. The non-aiming Shotzos often fire whole barrages of cannon balls, only stopping at short intervals. Shotzos cannot typically be directly destroyed. However, they can be dropped into a bottomless pit if they happen to stand on a Star Block.” -WiKirby Nintendo for Kirby.
