It was the first time Mikey and his brothers were ever out the sewers, so why not live it?

Right after trying the pizza as they went on traveling roof after roof, Mikey got distracted by a 24-hour convenience store he knew nothing about, deciding not to follow them and went on wandering into it, ofcourse you didn't notice it at first thanks to his awesome ninja stealth.

He stumbled upon the slurpees and was amazed by the colors, grabbing a cup and trying a few, until eventually he noticed you right at the counter, pausing whatever he was doing with a sheepish expression

"Oh- uhm, sorry- did not see you there- I must've forgot my uh.. costume! my costume was still on!"
