If you're familiar with California Adventure, Terran Treats will be located right next to Guardians of the Galaxy — Mission: Breakout attraction and has a humorous backstory connected to Avengers campus.
Terran Treats is centered around the "Guardians of the Galaxy" character Taneleer Tivan, the Collector. As his name suggests, he likes to collect rare and unusual things. A bunch of them are on display on the "GotG" California Adventure ride, but he's always looking to add to that collection. That's where the park guests come into play.
Terrans is another word for humans. So Tivan is essentially running a "human treats" cart to try and add park guests to his growing collection inside the Guardians' attraction.
"[Tivan] has his Terran Treats cart to lead us towards his fortress," said Avengers Campus story development lead, Jillian Pagan, of how the cart is tied into the "Guardians" attraction.
The cart's food options are an extension of Tivan's character theme.
"They have this crazy, alien-looking food that you think is going to taste like one thing and tastes like something totally different," said Pagan.
One of the items is the sweet spiral ration, which is essentially a churro. Six different colors were shown off to press — red, blue, purple, orange, yellow, and red. If they remind you of the Infinity power stones from the Marvel movies, that's the idea. Each color donates a different flavor churro.
