Master Splinter simply can't get enough of these new milkshakes Mikey has discovered. After letting sensei have a sip, something awakens within Splinter, something craving more. Soon, one milkshake becomes two, a small size becomes a medium size, two milkshakes becomes three, a medium size becomes a large size. More and more, bigger and bigger, just like Splinter. The ninjitsu master has been gaining a lot of weight, but what's wrong with that? Even if his kimono begins to get snug, or his stride turns to a waddle, he can't get enough of these delicious shakes. He'll need to thank Mikey, after a few more chugs.
