Escape the Island!

I shoot her, skin her, then use her inflated skin as a floatation device.
I leave behind a cannon to the moon (and it can only take you to the moon).

i shoot myself to the Moon and Build a Space Station.

i leave behind my Wallet

Obviously since im not as rich as everyone else you have an infinite wallet, and i make a pile of money and it attracts Bruce Wayne and he turns me into the new Robin since the last one died.

I leave behind the power for any 4 people to become my partners as the TEEN THAITANS!!

I use it to become beast boy, turn into a whale and swim home.

I leave behind a pile of tofu burgers and Cyborg (from teen titans, I loved that show)

I use the next great invention, Sand-Mini Shrinker Gun, and i fit into his arm cannon and he shoots me to Tokyo and they ship me to america.

I leave behind the Sand Mini-Shrinker Gun.

i shrink myself with the Sand Mini Shrinker Gun and become light as a Feather,i then run across the Sea Luigi style.

i leave behind Luigi.

Luigi shots me with his fire ball and i fly away Mario style

I leave a book (It can be any thing)

Since the book can be anything, it becomes a jet and flies me to Europa.

I leave behind anything that can be a book.
