This cup was supposed to be on display wherever ICEE drinks were sold.
The usual answer to that is 7-11 stores but...did you see it? The cup was submitted in March 2020, surely far later than it debuted in stores so what happened to it? Did it not have a wide release? Surely at least a few Sonic fans were near a 7 11 to see this thing or collect it by getting the frosty beverage/ice thing...seen here in appropriate blue.
It's a nice up too, for a promo like this. It's got CG art of the cast with Sticks too, and the logo at the top. It has Sonic activating the ring magic from the game, and proabably the rating for the game in black and white there at the bottom?
That it's "game based" rather than "show based" probably puts it even earlier in time because when the games were revealed as flops, the advertising and merchandise focus went to the show which was actually funny to watch, but didn't feature much of the game's mechanics and hallmarks/calling-cards (Ex. they weren't always using ring magic /shooting lightening out in the show)
