Family Guy...?

I just got the Family Guy game for ps2 and i am stuck on a level and cannot figure it out... I am where Brian has to go through Jolly Farm Review to get the 3 tapes and I cannot get through it without getting caught by the pig, the girl or the kids... I don't know what i need to do! can anyone help me... I can't find any cheat codes for this game that would help me out...

Thank you so much for your time...
