Adventure Comics #225

Professor Lang brings back a mynah bird that seems to have super-powers and human intelligence. It's stolen by a crook who paints it in Superboy colors to steal, so Superboy is blamed. Turns out the bird drank from the same African pool as \"Chandu, the Gorilla with X-Ray Eyes\" (seen in Adventure Comics 219). Superboy over-exposes the bird to the fallen meteorite and it reverts to a normal bird.
