Groske

The Groske (not to be confused with the Graske) were small, blue humanoid creatures.

Biology
The Groske were small compared to humans. They had pebbly blue skin and three tentacle-like features on their heads. They could smell artron energy, which they found unpleasant.

The Graske were related to the Groske and nearly identical, though brown in colour. The Groske disliked the Graske. (SJA: Death of the Doctor)

Technology
The Groske were technologically capable. The Groske stuck on Earth built a rocket to launch the Eleventh Doctor into space. (SJA: Death of the Doctor)



History
At least three Groske were stranded on Earth in 2006. They were found and recruited by UNIT.

In late 2010, the Groske worked at UNIT Base 5, helping out with UNIT and the Shansheeth's funeral for the Eleventh Doctor. One of the Groske knew the Doctor was alive and was returning to Earth because he smelled the artron energy on Clyde Langer. Later, when Clyde, Rani and Santiago tried to follow the Groske, they eavesdropped on the Shansheeth. The Groske also helped them escape. (SJA: Death of the Doctor)
