I've recently noticed that Steve's left arm has become bloated and misshapen. He has been refusing food for about 5 days now - he either swallows it, only to spit it back out after a few minutes, or just spits it out straight away. He's trying to eat, but it's as if he can't. Other than that, he's been behaving normally. Here are some pics: https://imgur.com/a/ACYMy
