A little Psychonauts X CTCD scenario me and Ironchef13 came up with.
—————————————————
It all begins when the Motherlobe is hosting their weekly movie night for psychonauts junior and senior, as well as inviting the Aquatos. Raz however goes to bed early after a long day of doing tasks for Sasha and extra acrobatic sessions with his family. However just as the movie begins all monitors in the motherlobe start acting up (Oleander even tries to fix it by whacking the main dorm TV, calling it the magic touch) before playing a commercial for a brand of flan, a Spanish/French/Japanese dessert, called "Flan-tasy Flan" and then hypnotizes everyone watching to have an uncontrollable desire to eat flan.

The next morning, Raz wakes up to see the Motherlobe in chaos. Containers of flan are everywhere and whoever isn't gorging on flan is scrambling to find more like desperate junkies. He meets up with Lili who has flan smeared on her face and pajamas and a pot belly asking Raz if he has any flan. Getting more worried by the minute, Raz races to the Aquato camp to see his parents and siblings also in a flan craze. After being interrogated by his own family they run to the nearby town for more flan. Well at least not everyone here was affected. Raz remembered that ford and Nona were out at whispering rock on a weekend retreat, Bob and Helmut were taking a hiking trip and Compton and Cassie were out visiting what is known as the biggest bee farm in the east coast. Just to make sure they don’t fall under the spell, he contacts them and warns them about what’s going on. Six of the psychic seven understand and promise not to watch that commercial until they get back and try to put a stop to this madness.

The next morning everyone in the motherlobe has become morbidly obese from the all-day flan binge, With the Aquatos having practically become immobile. Deciding enough is enough Raz looks into where this flan is being made and goes to confront the company after finding the address on the containers. Lili, having become obese but not immobile, joins him thinking they can get more flan. Since Raz isn't old enough to fly the jet, he and Lili take a bus to Flan HQ. Hours later into the late afternoon they arrive. Sneaking through the place via invisibility, they saw sights like the staff are practically flan zombies themselves and random people getting kidnapped and dragged in forced to be test subjects for this dessert, until they find the CEO, naming himself the King of Flan, who is hypnotizing people into becoming addicted to Flan through his commercials. He even hacked the Motherlobe to gain access to the monitors, that's why everyone became "Flan-atics" overnight. His goal is for his company to be the most popular in the country and make lots of money selling addictive flan. Now he plans to air his commercials all over the networks all throughout the rest of the country.

Raz tries to confront this dessert kingpin but not before he witnesses a commercial and gets hypnotized as well. The King of Flan catches the kids and offers them more flan. Lili eagerly takes the flan but Raz is trying hard to resist and fight back, but the King of Flan rolls into a ball attempting to flatten the boy. What comes next is a long battle with Raz dodging the King’s rolling attacks and psy blasting him to no avail. when Raz is finally cornered, Lili, having snapped out of her trance seeing raz in danger, uses her newly added weight to tackle the King and send him through a wall. Then using Herbaphony, controls vines from potted plants to tangle the king up. (She even gets mad at how expensive chocolate flan will be) The King then gets a taste of his own medicine, being hit with his own hypnotizing commercial and becomes a flan craving zombie. With that taken care of, Raz and Lili then broadcast a new commercial breaking everyone out of their trance, including the factory staff and test subjects who are free to go. and before leaving stumble across a whole warehouse of flan. Still under the effects of hypnosis Raz and Lili stare at all the flan with wide eyes and watering mouths. Back at the Motherlobe everyone snaps out of their trance and are shocked to see how big they've gotten with Dion saying Frazie looks as big as a house and she replies "Look who's calling the kettle black" back at him. In the midst of it all Queepie and Mirtala say "Where's Raz?”

Back at Flan HQ, Raz and Lili are gorging on Flan both having become massive blobs. Even their archetypes feed them.
The story ends with Raz saying "Victory never tasted so Good" with Lili letting out a large burp.
