I've observed that my beardies like "toys" that make specific sounds when crawled over or through, or when "kneaded" ie bubble wrap, screwed up crumpled paper sheets, hollow metal tubes
They also like tactile things.
Puff when I was still using a dome reflector for his 13W UVB200 and had the dome and UV globe suspended pendulum style from his rearing tub's lid loved to play with the dome, he's start it swinging by patting it with one of his hands and then nudge it with his nose, sometimes this went on for 30 minutes. Then daddy took away his favourate toy by replacing the dome with a NanoHood and upped to 26W UVB200s.Try as might because it was secured by 2 screws to the lid, he could not make it swing , he could still reach it is he stook up and stretched , and after a few weeks he gave up trying.
You can try a ping pong ball, if it has some grains of rice in it , the sound of it when they knudge it or bump it might intrigue the beardie.
I find the best entertainment and enrichment for a beardie
>> is a daily free range in a safe area of the house ,
>> a floor level window he can look out and watch the world outside, the birds , the wild lizards and people outside,
>> being able to watch his humans doing stuff
>> being able to watch TV.
