Cheep-Guava

Cheep-Guava is a Yehat character, possibly of the Zeep-Zeep Clan.

If The Captain incites the Yehat Rebellion, Cheep-Guava is the leader of the Yehat Rebels, and possibly the Yehat to whom The Captain shows that the Shofixti are alive.

Given the context, the name is most likely a playful pun, referring to the 20th century revolutionary Che Guevara.
