Maple Syrup is K'nuckles' favorite beverage. Every time K'nuckles drinks them, he rumbles mostly. A few episodes he drank most of the Maple Syrup most noticeably, Eye Sea You. Maple Syrup comes from Maple Syrup Island that is ruled by Flapjack's old plate of flapjacks he never got to eat (formerly ruled by Lord Hotcakes)
Maple Syrup is based on either Root Beer or Rum. In "Who's That Man in The Mirorr?", K'nuckles said that there is also his diet brand of Maple Syrup.
