Next year, open Onett General before the hunt and use the back room as an egg-painting station
Walk up to a desk and touch an egg to enlarge it on the screen as a blank canvas and let players use a pen tool (like on UN and other servers) to design and color eggs

Let staff review the completed egg designs (since half of you will draw penises), export the quality ones as PNGs, and then mix them all into the pool of eggs for the egg hunt, would be a very cool use of the egg stands

I'm sure they'd all look like garbage though since a Graal pen tool can hardly compare to any dedicated graphics software
(unrealistic expectation that requires a buttload of scripting)
