Yup, I just opened a can of worms. But do not worry, I will graveyard this thread 24hrs after existing.

I was playing the Concrete Jungles today. You know the Broken Messed Up city filled with the poisoned undead? Well, I didnt think too much of it, (Concrete Jungle, by definition means City. Just City)
But my cousin, shes a HUGE Bob Marley fan, noticed me and asked me what i was playing, I told her Spiral Knights but she was more intrigued in the level design so I told her, "Oh its this undead city called the Concrete Jungle" She then told me that the Green color reminded her Bob and the map name of the song Concrete Jungle. And then she starts singing it. Shes a good singer :) I googled the song. Here it is:

♫I said that life (sweet life) must be (got to be) somewhere to be found (out there somewhere for me)
Oh, instead: concrete jungle (jungle!) - collusion (concrete jungle!) -
Confusion (confusion). Eh!

Concrete jungle (jungle!): we've made it, We've got it.
In Concrete jungle (concrete jungle!), now. Eh!
Concrete jungle (jungle, jungle, jungle!).♫

Now Concrete Jungle has Poison Status. Could we associate poison to drugs? Bob Marley is well known for drugs [and the color Green]. and writing a song called "Concrete Jungle". Coincidence? or just trying to find some bad in a harmless game?

Think about it: Concrete Jungle. Color Green. Poison. Toxigels. song with identical name. Weird huh?
