Trivia
"Loca" is the Spanish word in female for "crazy". Her name is probably a reference to when people compare someone crazy with a cuckoo bird.
There was a long running gag in the series where Cuckoo-Loca makes sarcastic remarks about the Happy Helper's jingle, once Minnie and Daisy are finished singing it.
She has the exact same New York accent as that of Sticks the Jungle Badger from Sonic Boom, who is also voiced by Nika Futterman.
Although she met Minnie and Daisy in Happy Friend-Aversary, Cuckoo-Loca was shown with her friends and their boyfriends as infants in Happy Thanksgiving Helpers!.
