I need good ideas for english class

so I have to do a story for my english class and I am having trouble
I am not creative as a writer, but we have to do a superhero story
I want to have some fun with this to make is bearable

the superheros are crayons, The Crayon Clan(I am not that...

good a drawer, so I think crayons are the easiet thing to draw because I have to make a picture of them)
and there enemy is White Out Willy
(a friend came up with that?)

and I cant come up with a good story outline
it can start out any way
but in the story
there has to be a point where it LOOKS like the crayon clan will lose
but something superduper happens and they win in the end!!

and I need a little help with any more ideas.

as the crayon clan looked over the horizon past their land they saw the destruction white out willy had done and knew that he/she had to be stopped.(thatd be like the intro.) then get into it ya know?
