I've tried this level several times now, and I just can't seem to beat it.

I can't get past the school yard fence, and I can't seem to get on top of the building to get past the barrier that the King points out.

Any tips?

roll around gathering stuff. make sure you get all the sunflower plants, people, fences, vehicles, etc, this will increase your size quickly, but will only tempporarily inconvenience you. the pedestal you start on helps too. make sure you cover the main area, the town above, and where the stuff falls on you near the fence you can't pass, there's a chicken pen if you need size fact when you're small-- you can swim to it. ok. gather all that gunk up until you're about 4m. climb over the green fence, grab the people, take a sharp left, and follow the building till you see a brick wall with a hole in it. go through the hole, up the incline, and you're into the 'free for all' portion of the level-- which the King seems to indicate is best got to by going up that building--wrong.
