Who Keeps Taking Biscuit's Clothes?

It seems that Biscuit it the target of clothing theft. I've noticed as I've drawn him here and there. So now he has no clothes lol. I know the there is something wrong with it, but it doesn't bug me too much so if you do know, please don't tell me. So now he is embarrassed again and his cute little bottom is exposed. It was also a bit embarrassing to draw this but I thought it was cute. He's trying to cover it but his little arms are too short.

I now know how plain he looks without clothes...oh well enjoy!
