Give the Boy a medal

I've invented a new Olympics sport. 
First, you have to run really fast around and around three times so that the ninja fish can't bite you.
And then you have to kick the slidden fish. The slidden fish is dead.

Further details are still quite confused at this point.

Daddy's trying to figure out how you win. But you know you're finished when the ninja fish is dead. There's also a ninja tower, which attacks the dead fish. And then says sorry.
