Blatzy is an obscure cannon-like enemy which appears in the Extra Game of Kirby's Dream Land and in Revenge of the King from Kirby Super Star Ultra. It looks and behaves very similarly to Shotzo, being an all-but impervious stationary cannon with the ability to aim its cannon and fire at Kirby, and replaces its more familiar counterpart in the game modes in which it appears.
Appearance and behavior
Blatzy resembles a stationary cannon with a thick cylindrical barrel atop a triangular base. As such, it is distinct from the more rounded and modest Shotzo, and looks more mechanical. Blatzy also bears a somewhat bluish coloration with a bright yellow bolt connecting the barrel to the base.
Blatzy is notably faster than Shotzo, both in its ability to pivot toward Kirby and in its fire rate. This makes it considerably more difficult to pass a Blatzy than a comparable Shotzo.
Kirby's Dream Land
Blatzy appears in Kirby's Dream Land's Extra Game, replacing Shotzo wherever it would have been in the normal mode. Like Shotzo, it can only be killed while Kirby is under the effect of the Invincible Candy by standing in one for a few seconds. This can be seen in Castle Lololo where the Invincible Candy and a Blatzo exist in the same room. Blatzy appears in every stage except for Mt. Dedede.
Kirby Super Star Ultra
Blatzy appears in place of Shotzo in Revenge of the King. It is also not totally invulnerable here, as it can be defeated using the Mike ability as well as by running into it under the effect of Invincible Candy. It cannot be defeated using Crash, however.
Blatzy appears in the Illusion Islands and Crash Clouds stages.
