While Cherry and berry look like a pair of sour gummies that didn't get fully separated at the factory, they're actually just little alien worms. You see, Cherry is the blue one, and Berry is the red one, and in their world, two heads per body is the norm. Berry however, is jealous when he sees other creatures who don't have to share a body with an annoying brother. There's a lot of things Berry doesn't understand, like why his brother, Cherry, called dibs on such a name WHEN HIS SIDE IS LITERALLY BLUE?? But he'll bare with with it. Cherry is a goofy little lad and secretly, Berry really does care for his brother and not even because they share the same body! They're buddies, and although Berry can be kinda a meanie who will never admit that, he cares a ton for his brother, nothing will ever change that.
