The Froog are an animal-like species from the planet Linkit. When constructing the Codrex, the Great Beings placed some Froog, Agrippa, and Crystal Serpents on the sub-levels to act as guards. Thousands of years later, a Makuta tried to access the Codrex files, which caused a Froog and three Agrippa to be teleported in. They were killed during the battle.

Froog are similar to frogs and can jump far distances.
