It's a ship carrying animals so you never know when something unexpected might happen where one gets out and you'll need to neutralize it so the tranquilizer is just a good precaution plus not a bad idea to have it handy. As for why he's moving besides it just being a game mechanic to make it more fun: he sees an animal using a weapon/tool that can harm him so he's probably trying to distract/confuse it along with potentially trying to get a better shot to neutralize the threat.
