Ice Cannons are an obstacle appearing in Papa Louie 3: When Sundaes Attack!. They're basically the same as the Cheese Cannons from Papa Louie 2, except they shoot ice instead of cheese. When the player is hit by an Ice Cannon's shots, they'll be frozen and have to jump three times to thaw out.
Radley Madish also uses an Ice Cannon during the second phase of his battle. After losing some health, his radish rocket will sprout an Ice Cannon that occasionally shoots ice all over the room to try and freeze the player.
