Seems like you have social sugar gliders. Yay! You'll figure out how to handle their unexpected attacks eventually.
They might be playing with the toys when you're#8203; sleeping. I didn't think mine played with theirs until I have them toys with bells and stuff they can take apart. I heard the bells and could see the toys in different parts of the cage.
My male loves my phone. I thought it was because he's a turd and enjoys doing things to annoy me XD.
Seems you have some spunky gliders :)
