During the scene where Sonic is about to leave on a mission to Robotropolis, Uncle Chuck says "come on boy, jelly and jam time!" in which case, Sonic corrects him by saying "That's JUICE and jam time". This is a reference to Ben Hurst accidentally writing "Jelly and jam time" a few times in Sonic the Hedgehog (1993) in which the correct phrase is also "Juice and jam time".
