Oh and make sure your hands don't smell like food, or that you use any fruit-scented soaps or lotions... That can encourage him to nibble to get a taste!
For toys, check out your thrift stores for plastic baby or toddler toys, floor toys and baby links make great sugar-safe toys. Just remove anything with batteries, or moving parts that could pinch tiny fingers or tails.
The dollar store is another great place to sugar shop, little baskets can be hung around the cage, plastic vines with no metal cores can be hung for climbing, pom poms make great ball pits, army men, plastic bracelets, any plastic children's trinket type toy is great or them to chew on. Monkey in a barrel, hang the monkeys for your gliders to knock down an carry around. After a while, you'll get an eye for anything that will make a good toy; they are very easy to spoil!
For free stuff, they like plastic drinking straws and milk jug rings. I've also made ball pits out of old milk jugs, just cut holes for them to climb in and hang from the handle. Stuff with straps of fleece, plastic kids toys, and some treats for them to dig throufh.
But the number one favorite toy for gliders everywhere is a sugar safe wheel! They will live in it, I swear. We have stealth, raptors and custom cruisers here, and they all get abused nightly :)
