Was Wondering Is Lychee Is Okay For My Sugar Glider When Ever I Eat One He Just Looks At It Like It's Gold

Yes, it is okay and they usually like it.
However, I'd advise to give it only as a treat under supervision (one of my gliders once brought his piece of lychee in his sleeping pouch and slept on it... the day after he looked like a hedgehog because all the fur on his back was glued dry in a spike like appearance...)

LOL!
