Videogame Cage
If I had to be stuck in any video game, it would probably be Super Mario Bros. Why? There's so much to do with so many different worlds, I'd never get bored.
Also, being stuck in a Mario game, I too can help fight the boss monster, Bowser! That is something that I've always wanted to do, and with effort as little as jumping on his head. I'd have a blast being stuck in a Mario game, jumping on everything that comes into view. I'd even dress for the occasion and get my own Mario suit, maybe a blue one because I don't think that one has been taken yet.
I'd love to obtain the same power ups that Mario's world has access too. My favorite would proably be the mini power up as it makes you extremely small, but very light, fast, and the ability to jump extremely high. I feel like I'd have a blast using that ability in any world. Another ability I feel as if I'd have a grand time with would be the propellar cap. All I would need to do is spin and "WOO!" I'd fly into the air as high as the eye could see, and not a single monster would be able to get there hands on me. And of course, the classic fireball ability. Who hasn't dreamed of controlling one of the elements and bending it to their will? This classic ability will allow me to control the element of fire and burn my enemies to a crisp.
Finally, I'd have the responsibility of saving Princess Peach, which is really cool if you think about it. Saving an actual princess! Of course I wouldn't be able to make a move on her because that's Mario's girl, but it would still be a really fun experience!
