Phobingo is a game of Bingo that June gave Maxx off-panel. It is basically a game where you find a line of things that scare Cyril .
Origin
On comic #343, Cyril's robe wizard pyjamas catch on fire while being melted out of the cube of ice he was frozen in.
Later, a user known as JakeMorph decided to call it Phobingo, a mix of words "phobia" and "bingo".
