Cactina is an imaginary friend that appears in three episodes of Foster's. Her name was revealed in the card in "Goodbye to Bloo".
Appearance[]
Cactina is an imaginary friend whose body above the waist is made of a cactus. She also has light green legs and a pair of lips that have a mind of their own. She wears red high-heels with flowers on them and a chartreuse straw hat.
History[]
Cactina first appears in "The Trouble With Scribbles", where Bloo asks her about the home's secret door. Just before she reveals the door's contents, her lips detach from her body and run off, making her run after them. Her lips reappear in Bloo's nightmare that night.
She later cameos in "The Big Picture", where Mr. Herriman assigns her to be in that year's group photo. Despite this, she is not seen when the photo is about to be taken.
Her latest appearance is in "The Bride to Beat", where she tries to get Bloo's attention, only for him to make her trip and fall down.
