Sorry, peeps. Somebdoy made this adult text! and it is implied this isn't the only time this has happened. When Phil obtains a slip of paper with Richy's locker combination written on it, it looks like it says "BLOBBLES", when in actuality it is "53788078" because Phil is holding the slip of paper upside-down.
Richy's locker combination is based on JonBro's obscure series of short Flash movies called Blobbles. JonBro decided to use the phrase as a locker combination when he realized he could spell out "Blobbles" upside-down on a calculator.
Richy was a high school drop out. He was too focused on collecting buttons.
As proven in Riddle School 5 though, it turns out all of the past games since one are a dream conjured by the Alien Viz.
In Riddle Transfer 2, it turns out he actually shares no interest of buttons with his dream counterpart, he gives the player glue after being given a recently obtained dollar from Chubb (from Riddle School)
