Constance[1] "Connie Lingus" LaCienega the Hormone Monstress is a female hormone monster, who helps girls (mostly) go through puberty. She works as Jessi's (and briefly Nick's) hormone monstress and serves as a foil to Maury, who she has an on & off sexual relationship with (as well as a child). She embodies the part in many women's mind yearning for independence, glamour, and sexiness. She has some catchphrases, such as "Let it out", "What in da fuq!?", "Get rid!" and "Bubble bath" (pronounced "bubba baff"). She first appeared in "Everybody Bleeds". She is perfectly voiced by Maya Rudolph.

Connie is a tall and slender vibrant yellow hormone monster with very long, prehensile, knee-length maroon hair and tawny brown curvy body fur that covers her breasts, arms, legs, butt, and also serves as her eyebrows.

She has a wide nose with pronounced nostrils, that sit above her broad mouth, rimmed with dim fandango lips. Connie's hands are small, pale, and yellow and she has yellow hooves for feet.
