Caterpie in a Fantasy world

Yo the name's Jay and I'm a human or at least was a human until I got mysteriously teleported into another world in the body of a weak creature. Luckily for me it's a one that I'm familiar with. So with the help of this weak yet potentially strong new body and system who is a real pain. Let me sleep through the journey and hurdles I shall face to become a supreme being or maybe even sleep with one. Cough cough...
