Mama is the secondary antagonist in the 2020 Disney+ animated film Phineas and Ferb The Movie: Candace Against the Universe. She is an alien spore plant that acts as the source for the Super Super Big Doctor's reign in the planet Feebla-Oot.
Becoming the Big Doctor's Pet
Mama started out as an unnamed spore planet living in the Big Doctor's former world, where the Big Doctor learns that she feeds off on a certain gas called "Remarkalonium". which will allow the plant to create spores on the populace and make them obedient to those who controls her.
With that in mind, the Big Doctor named the plant Mama after her own mother and used its spores to take over of the planet Feebla-Oot, enslaving its previous rulers (known as the Cowards) and ruling the planet with an iron fist.
It wasn't until one day when the Big Doctor kidnapped Candace Flynn-Fletcher and Vanessa Doofenshmirtz and brought them over to Feebla-Oot, as Candace contains massive amounts of "Remarkalonium" that can support her people, thus making Candace very special. The Big Doctor also sympathized with Candace by admitting that she had two younger brothers that she felt tired of, which inspired Candace to have a fun time with the Big Doctor.
However, Candace learns that "Remarkalonium" is actually carbon dioxide and that the Big Doctor is feeding Mama with large amounts of it to use the spores to control her subjects and keep them in line. While confronting the Big Doctor for this, Candace accidentally spills out that billions of people on Earth exhale carbon dioxide. Upon hearing this, the Big Doctor decides to plan her next move to take over Earth by unleashing Mama there so that she can create more spores to make humanity bend to her will. As such, the Big Doctor takes Candace into custody while ordering her army to prepare for an invasion on Earth.
Eventually, Candace's brothers Phineas and Ferb teamed up with the Cowards to attack and reclaim their city, but the Big Doctor and her army have fled for Earth with Mama and a captive Candace in tow. Learning about the Big Doctor's true plot to take over Earth for its carbon dioxide, the gang flew back to Earth to stop off the invasion while freeing Candace, who reconciled with them before they are captured again by the Big Doctor's troops. As Mama unleashes more spores in the Earth, Candace tries to convince the Big Doctor in giving up her plot, but before the Big Doctor could accept this, Mama has overgrown due to consuming too much carbon dioxide and went out of control by devouring the Big Doctor whole, something which the gang didn't expect.
Though it would seemed that all hope is lost as Mama continues spreading the spores and wreaking havoc in Danville, Vanessa's father Heinz Doofenshmirtz has returned back to Earth with Vanessa and Perry the Platypus by creating an inator that swaps something with the closest or farthest chicken. As the initial chicken still resides in Feebla-Oot, Doof gives the inator to Candace, telling her to set it to the furthest chicken to send Mama back to Feebla-Oot. Candace does so, and Mama ends up being transported back to Feebla-Oot, dispersing all the spores on Earth for good. Upon being transported back to Feebla-Oot, Mama shrinks down and regurgitates the Big Doctor. Mama then gets squashed to death by an elephant creature, and the Big Doctor ends up being arrested by the Cowards while her remaining forces end up being detained by the authorities on Earth.
