"The Royal Jelly's caption "The king of all jellies... that is, until you meet the queen." is a reference to two enemies from Nick Popovich's previous game, Spiral Knights; the Royal Jelly and the Ice Queen."
Sounds like Nick himself just called the Royal Jelly the "king of all jellies" implying that that Royal Jelly could perhaps be... the Jelly King?
