The only viable alternative question I can think of that Jordan might have a chance at would be, (Chen) "Guess the color of Greens".
(Zazzy) "Apple"?
(Chenbot), "No, not 'apple', that's not really a color".
(Icey) "Red"?
(Chen"bigbelly"bot), "No, not 'Red', that's not, er, green".
(Snidge), "Yellow"
(Chen"bigbellybutton"bot), "No, not 'yellow', that's a banana (but hold onto that for a future "Casey" related question)".
(Jordan)"What are greens, Julie?"
(Chen"bigbellybouttoburst"bot) "Congratulations, Jordan, you win part 2".
