Michelangelo's Birthday

It's a very special day for Michaelangelo... only his brothers seem to have forgotten all about it. Unknown to Mikey, the other Turtles are only pretending that they have no idea it's his birthday, in order to launch a surprise party on him later. As the day progresses, and Michaelangelo gets more and more irritated and upset, Leonardo begins to feel as if he, Raphael, and Donatello are stretching the joke just a little too far. But his concerns are ignored by the others, who believe Michaelangelo's present state will make his surprise party even better. Michaelangelo, depressed and frustrated, surprises them all before they can surprise him…by running away! Before they can go after him, the remaining TMNT hear reports of Shredder, Rocksteady, and Bebop, embarking on a rampage through New York. Splinter volunteers to locate Michaelangelo, whilst the remaining Turtles do battle with "Tin-Grin". Shredder has armed himself, however, with an offshoot of the same mutagen, that once transformed the Turtles from tiny babies to their present martial-arts kicking state. He tries to use it on the green machine during their battle, but the Turtles are too fast for him. and his force retreats. On his way though, he bumps into Michaelangelo. Subduing the turtle, Shredder straps him to a device that begins pouring out the mutagen! Will Michaelangelo spend his birthday (and the rest of his life) looking like he did on the actual day he was born?
