FSTS: Updated Story Development

I have revisited some elements of my story development. I have updated my logline and step outline and have created short character bios. I'm not sure what to do about a premise, as I think that's supposed to be a starting point for a story, and I'm not sure if coming up with one now would be strange. I think it would have to have something to do with envy, because that's been a theme for a few versions of this story.

Logline

Momo and Pogo are no strangers to sticky situations in their circus routine, the custard pies make sure of that. But Pogo's feeling mistreated, and Momo finds himself a little stickier than he'd anticipated.

Character Bios
Pogo is a tall, skinny clown, he wears green and often arches his brows. He has a bit of a mean streak and doesn't like it when things aren't fair. He loves his work at the circus, but he feels let down by his partner.

Momo is a short, fat clown, he wears red and often stands with his feet together like a penguin. He has a bit of a mean streak and likes to be the center of attention. He loves his work at the circus, but he doesn't care about his fellow performers.

Step Outline

1.  A poster shows details of a circus, there is a drawing of a tent at the bottom. The tent dissolves into the real thing. It is evening and there is light spilling from the entrance. 
   
   
2. Momo and Pogo are performing their show in the tent, Pogo slips on pies but dodges a vicious machine. Momo's wig is caught by the machine but comes off. Pogo takes his wig off and the audience laugh. Momo pushes Pogo back with a bow. While Momo continues to joke, Pogo cleans with a sponge from a locker. 
   
   
3. The next evening, there is light spilling from the entrance to the tent.
   
   
4. The events of the previous night repeat, this time Pogo seems annoyed, and he cleans with a mop from the locker.
