who is this strange turtle

part 1

when i was in the middle of my training when a portal opened up in front of me and started to suck me in the wind was so strong that i was in the different place within two seconds. when the portal closed i was in a new place with a lot of buildings, flashing lights, and honking cars everywhere. my head was spinning when i woke up i was in the sewers?   it may have been really blurry but i could still kinds saw sewage water and i just contacted the dots

out of the corner of my eye i saw a human sized turtle in a purple mask and on his left was a orange one on the right a blue one.when the lights came back on i was in a afermary with four beds around me with names on them Leo,Donnie,raph, and mikey my head spun more who where they and where am i thought to myself but before i could ask they answered my questions.Now that i could see them clearly the first one i noticed was a tallish one with one green eye and one blue eye, two red what looked like lines on his face along with a mug look with a ciriouse exspetion on his face looking at me. I don't know why but i  felt butterfly's in my stumic when he looked at me so to avoid those felling i looked beside him and saw another human sized turtle about the same height  with deep dark brown eyes, a purple mask, and goggles on his head with a "why am i here" kinda look on his face then i went to look at the third one but before i could he was already right in front of me he looked like a maniac him eyes wide like he was at the candy store 

_a few hours later_

i got up to ask for some food  but instead i saw the blue one next me i asoomed that his name was Leo guessing by the name tag on him his cloths and i stared to fell butterfly's i stomic and i didn't know why. well it seems like he didn't notice because  he was talking to me normally not like most people would and that just made it worse"hey i'm Leonardo but you can call me Leo" what your name" Leo asked out of the blue"oh yeah my names usagi nice to meet you"i said my voice quivering  because of how nerves i was "oh that's a cool name"Leo said with a big smile on his face that made my heart melt "so how'd i get here?" i asked "i don't know i just came in here when i saw Donnie brought home a friend then i saw you an-"he cut off "then you?" i asked him but he didn't answer he just changed the subject
