DS1 is turning 4 in May, and we are having a farm party!

I will have about 2-3 hours on the Friday night to cook and prepare things for it, and about an hour Saturday to put things together ...

While I'm an ok cook, I am not the farm animal decorated cake pops with tempered chocolate and coconut tuille kind either ...

I'm more of the chocolate crackles, fairy bread and cob loaf dip style ...

But I'm up for ideas!

What will be easy and cheap enough to put together, will travel well (an hours drive or thereabouts), and will be happily devoured by 4yos and their folks?

I'm making food for about 30 - some sweet, some savoury, budget is $50-100 (not including cake, which we'll grab from Costco for $27).
