Fresh Air
Mikey was brought out of his sleep when he felt one of his brother's shifting around. They had all decided to make a giant nest and sleep together like they would when they were kids.
Mikey rolled over and rubbed the sleep from his eyes. He watched as Leo walked away from their nest and out into sewers. The youngest got up and followed his oldest brother. Making sure to keep a discreet distance from him.
Leo stopped at a manhole exit and climbed up. Confused, Mikey quickly followed and found himself topside. Leo had stopped and just stood in the middle of the street, his back turned to his youngest brother. Deciding to reveal himself, Mikey climbed the rest of the way out of the manhole and approached the blue turtle.
"Hey, Leo, what are you doing up here?" Mikey asked. "Did you need some fresh air? You're not leaving are you?"
"Mikey?"
Said turtle turned around to face his two older brothers, Donatello and Raphael.
"What are you doing all the way up here?" Donnie asked. "Come back to bed before you catch a cold."
"Sorry I woke you both," Mikey replied, with a smile. "I just needed some fresh air."
