Idikiukup and Bob

Idikiukup and Bob are twins from Centauri B who work as technicians in the MiB headquarters.

Men in Black
They first appear in Men in Black. They can be seen operating consoles and giving information to agents. They were the ones who conveyed the message that the Arquillian ship was in orbit over eEarth and would begin an attack if the Galaxy was not returned to them.

Strangely, the twins made no further appearances in the two sequels.

Animated Series
They appear later in Men in Black: The Series continuing to work as informants, giving information to agents. Bob is shown piloting a helicopter in the episode "The Fmall, Fmall World Syndrome". Both are shown in a later episode piloting a spacecraft.

Trivia
The name of one of the twins differs in the first movie and in the cartoon series.
