Gruntling

Gruntlings are enemies that appear in Gruntilda's Lair in Banjo-Kazooie. They appear in every world of Banjo-Kazooie: Grunty's Revenge. As their name suggests, Gruntlings serve as Gruntilda's basic minions. Gruntlings are cloaked creatures, and each color of cloak represents how strong they are. Red-cloaked Gruntlings are the weakest, blue-cloaked Gruntlings are medium-strength, and black-cloaked Gruntlings are the hardest to kill. Two extra colors were added in Grunty's Revenge: brown-purple and gray, which require 4 and 5 hit points respectively.

According to a Jinjo Oracle, Gruntweeds are the result of combining Gruntlings with Whiplashes.
