Hoove activating the LFR
A Life Form Reader was an item of technology used in The New Adventures of He-Man.
On the planet Rintor, the evil Skeletor ordered Hoove to use a Life Form Reader to make sure all of their enemies were located in the Great Hall. However, Hoove was surprised when the LFR picked up life form readings underground. Flogg didn't care, but it intrigued Skeletor.
