Ravage will, in fact, play with laser pointers. Only in private, and only when he’s feeling energetic, but he will. Rumble and Frenzy are not allowed to hold the pointer, though, because they like to get him wound up and then lead him to run into things. 

When Ravage was a tiny kitten, Soundwave would wrestle the tiny predator with his data-cables, after wrapping cloth or silicone around the parts in use to protect from tiny claws. They no longer do this because Ravage is too strong, but Ravage still automatically flops over and starts flailing at the air if he’s relaxed and something cable-shaped is wiggled over him. Pieces of thick hose will do the trick. 

Rumble and Frenzy like to get involved in Decepticon parties, especially the parts that involve boasting about one’s interface partners, and are protected from even the boldest opportunists by the silent threat of what Soundwave will do to anyone who harms them. No matter how drunk they are, they are going back to their quarters, and only back to their quarters, unless they decide otherwise. And Soundwave will still come scoop them up if they get drunk enough to be particularly stupid.

The twins tried to wrestle approximately everything when they were young, so Soundwave made them an ‘opponent’ out of a bundle of tubing, tied into something like a bulky pom-pom, that they could wrestle until they were exhausted without bothering anyone else. If he had to keep them occupied for an especially long time, he would hide small energon treats among the pieces of tubing, which would cause them to wrestle the toy in search of more until they were tired enough to just fall asleep.

Laserbeak is Soundwave’s oldest (followed by Ravage, then the twins), and he really didn’t know what to do with her for years. She didn’t mind, though, she didn’t know what to do either. They get along great, always have, but Soundwave was very confused when she was first born because he didn’t know what to do with a symbiote. Nor did he know what it felt like to birth a symbiote, which was extremely confusing at the time, and made Megaton incredibly concerned when his loyal friend started dripping fluid from his lower chassis. 

As a tiny, flat sparkling, Laserbeak couldn’t fly well, so she skittered around on her pointed legs most of the time. She looked like a little diamond with optics. Strangely enough, she absolutely adored being thrown like a frisbee, even though she staggered in crooked circles for quite some time afterwards due to getting dizzy. Soundwave was baffled by every aspect of this, but obliged her, albeit narrowing their bond considerably so he didn’t feel the wooziness. 

Soundwave and all the symbiotes have all seen each other in various states of nudity, including as armor-free as is possible for each frametype. Some of this is incidental, some of it is intentional- there’s no point in them being shy around each other. 

The symbiotes (especially the twins) tend to chat about their interface partners whenever possible. Soundwave doesn’t actively participate, but he listens if requested- he likes hearing that his little ones have been enjoying themselves. Even if the twins get very graphic and make him wonder where they learned to do these things.
