... the thing is, Daddy (who is also a fireman) was trapped in the Disgusting Rocketship by the evil cabal of bad guys named Captain Cardboard, Dr. Shoes, Super Ugly Face, and Captain Hide-Your-Underpants. The Disgusting Rocketship is really Daddy's bed, and he has this pattern on the sheets that kind of looks like a bunch of buttons you can push, so when you're in the Disgusting Rocketship you push a button and something disgusting (like cat poop, or sweaty sock juice, or rotten broccoli soup) falls all over you and gets you all dirty and gross. Luckily, the button right next to it is the one that sucks everything up right away, but it's sort of cruel because just when you think you're finally all cleaned up and presentable one of the bad guys pushes another button and BAM you're all yucky again.
So Daddy was trapped in the Disgusting Rocketship when Super Zap and Superman came along to save him. Except that Super Zap decided he wanted to put his Spider-Man costume on and become Spider-Zap, and the extent of Superman's powers is to tell you who he is over and over and over again. But Spider-Zap and Superman acted quickly and leaped in to save Daddy from all the disgusting detritus torture, and it was working until the bad guys grabbed the super heroes and tied a belt around Spider-Zap's cape so he couldn't fly and threw them into the Disgusting Rocketship with Daddy. And the three of them protected themselves valiantly from the onslaught of rotten asparagus and used baby diapers until Spider-Zap thought of a PLAN! And he broke free of the belt and grabbed Daddy and Superman helped too and all of them were free of the bad guys! And they celebrated by raiding the Halloween candy.
So yeah, the backstroke will have to wait for another day.
