Reality:
Systematic:(Sunny Swamp)
Coco is a minor character in Candy Crush Saga. He is a 'little rainbow guy' and encountered in the 60th episode, Coco Crossroads. Before introducing level 876, he is crying because the arrows on the direction signpost are continuously spinning. After completing level 890, Tiffi brings a whistle. Then, she blows it and a bigger Coco-looking rainbow, who is probably his father, arrives and causes the signpost directional arrows to stop spinning. Coco throws the umbrella to the bigger Coco-looking rainbow which responds by twitching his eyebrows. Coco gets happy and makes a pose.
He appears once more on the replica of his debut episode, Sugary Skies.
He now appears in the April Fool's Day (2020) episode, Sunny Swamp, after just two appearances (or one since the second is a replica of the first). Hence, he is one of the characters to have only one flash appearance and multiple HTML5 appearances. He is the last episode character to be retained after April Fool's Day 2020.
Due to April Fools 2020, almost all episode characters (but eight) have been absent from the game. A few other characters make occasional appearances in events.
