Part of my level series, Mega Man World! (If you've played any other levels of mine, you know why I chose that name.)
Here, you're going into the Amazon to stop Tiger Man from stealing oil from an oil reservoir underground! Why? Well, oil helps robots and machinery stay able to move, and some things are powered by it.

Bonus Comment:
This level's quite hard without the Charge Shot. Playing as Bass made me realize that, so I made several sections A: Allow you to skip over the oil, and B: Get past all the Pookers easily. Are there any errors I made in the level, making it odd to play? Well, I was getting frustrated with having to go to build and edit and edit and edit my level... So, I hope you understand. I just needed to be done! (There's one black spot missing towards the end that got me really angry, but I calmed down quick because I wasn't going back to fix it. I was just crazy ready to be finished...)

I also accidentally discovered an easter egg for typing Mega and Marino right next to each other on WebMeka. It was weird. I don't recommend trying to do the easter egg.
