Although Gary still could visit for the eclipse or the Anniversary Party (along with other mascots), Gary is now confirmed to visit for the Halloween Party!
I’d like to thank Nandovshiki and TopHatNinja for informing me, as stu said the following:
Gary will be here for Halloween

It’s good to get confirmation on this, and you can view the Gary Tracker here. Thank you very much for reading, waddle on!
