CooKoo Bird



The CooKoo Bird is a small, blue bird that is a friend of Mario and Luigi on The Super Mario Bros. Super Show!, who lives inside their cuckoo clock in Mario Brothers Plumbing. The CooKoo Bird rarely appears, and when he does, it's only momentarily, usually to announce the time, or to alert Mario and Luigi about incoming subway trains from the nearby station.

Appearances
In the episode "The Mark of Zero / Toupee", the CooKoo Bird appeared to warn Mario and Luigi about the incoming subway train, which just so happened to be carrying Inspector Klean, who was on his way over to evaluate Mario Brothers Plumbing, and see if the place was up to code.

In "Star Koopa / Santa Claus Is Coming to Flatbush", CooKoo Bird came out of his clock to announce the midnight hour on Christmas Eve, indicating that it was now officially Christmas Day, and wished Mario, Luigi and Nick a Merry Christmas.
