Straight Flush

A.B.'s body is stolen by a plumber. When they go on an adventure, the plumber and Max trade, when the plumber finds a rare "hairball extractor". Then A.B. gets his body again. A.B. tells Max about being the baby, then Max says that FX and Max were born before him, so technically, Max says that A.B. is the baby, so they dress him as a baby. Max says that he and FX decide when A.B. sleeps.
