What's a Zook?
"A major change in the feature came with Detective #311, which introduced J'onzz's other dimensional buddy Zook. Zook had some wild powers of his own, including the ability to change his temperature from freezing cold to boiling hot, and to change his shape at will. He could also read minds with his antennae. Although able to talk he was portrayed as having the mind and affectionate nature of a small child."

It was the Silver Age. God only knows what they were smoking.
