The Hiisi Grenadier (in-game name Kranuhiisi) is a common Hiisi enemy.
This enemy will fly around and shoot what appears to be a grenade launcher, firing firebolt-like projectiles. These projectiles are affected by gravity, and do not travel far, so stay on the same plane vertically and attack from long range. Alternatively, the player can float directly above or stay directly below a Kranuhiisi, since they cannot fire their projectiles directly up or down. They behave like other Hiisi, as in they don't attack other Hiisi and may attack other creatures. They can often be found with others of their kind and Rynkkyhiisi.
Occasionally, they and Rynkkyhiisi will be found as part of a large group with a Toimari. One or more Kranuhiisi will also spawn whenever a Toimari is damaged.
