One of the greatest things about the public transportation system is that anyone can take it, and usually it'll get you where you need to go (albeit slowly). Public transport systems like subways and buses allow just about everyone to get from one place to another for a fairly affordable rate.

Now, the fact that public transport is so accessible is great, but it also makes for some pretty bizarre sights and scenarios. From time to time, something is spotted on a public transport vehicle that just maybe shouldn't be there. That is what the subreddit "Subway Creatures" documents.

When people see things that are a little unusual along their travels, they take photos to share with the rest of the internet for everyone to laugh at and enjoy.

There are plenty of entertaining and sometimes a little baffling subway creatures to see on Reddit. Here are just 15 of those curious critters as they take on what seems to be a wild journey.
