I can see a character like The Meal Vendor popping through with some really annoying ice cream truck music so you know he is there. Perhaps use a variation of the sno-cones already in existence? There is so much pop culture goodness in the ice cream cart/truck archetype!
+1 We should be able to make some ice cream or something like it, like milkshakes. Fruit changing into different fruits, add some ice, add some milk, pop it in the blender and viola!
