Sir Slush

Sir Slushes are enemies that appear in Banjo-Kazooie. They are found in Freezeezy Peak and the winter season of Click Clock Wood. There is also one that appears just outside of the Freezeezy Peak entrance in Gruntilda's Lair. Sir Slushes do not move around but instead roll up snowballs and throw them directly at Banjo and Kazooie. The duo must avoid being hit by them. Unlike most enemies, Banjo and Kazooie are not injured from touching Sir Slush; the duo are automatically bounced off instead.

Sir Slushes can only be defeated from Kazooie using Beak Bomb on the red "X" painted on their hat, while taking flight. No other attack can defeat Sir Slush, including Wonderwing. After being defeated, the Sir Slush breaks up into snowballs that fall in with the piles of snow.

Trivia

 * Sir Slush's weakness likely references Frosty the Snowman, who came to life from his top hat.
