Space Cuckoo (宇宙カッコウ Uchuu Kakkou) are a breed of aliens shown in the Keroro Gunso anime. The only one shown so far is Babubu.

TriviaEdit

  • The Space Cuckoo's behavior of leaving it's young in the hands of another alien species may be a reference to the Common Cuckoo, a species which also does the same tactic.
