Yes I had to gas mask them. I left the voice diaphragm off too so the masks essentially function as gags, muffling their wearers.

I wanted to do some really cartoony characters that could be put into lots of really cartoony bondage situations, such as a collection of crazy plants on their planet, or rubberising security systems. So here’s the crew to be at their mercy!

Slate - Second in Command on the ship, and probably not the best choice. Strong, but dumb. Likely to just look at you squirming asking for help and get confused because the gag stops you from specifying what you want. Luckily he gets the treatment himself more than a few times. Usually by disgruntled coworkers.
Hazu - The Captain, and the character who is almost always tied up in some way or another. He’s pretty forgiving though, even if his team causes him to be trapped for weeks in extreme bondage.
Taffy - Head scientist with a bit of a mean streak. Unlike Slate who just doesn’t get it, Taffy is more likely to laugh at you trapped and only help when he’s done having fun. Gets his comeuppance though.
Oka - Taffy’s assistant and usually the subject of his experiments. Oka spends almost as much time tied up as Hazu. He’s less tolerant though, and often schemes revenge against Taffy and sometimes Slate.
Manos - The strongest member of the team and pretty smart too. He perhaps doesn’t get bound up as often but he usually gets the worst punishments as a result when it is his turn.

I already posted one of these scenarios just a few days ago but I’m planning more and more for each member so stay tuned.
