You may eat the Pez now but eventually, the Pez will eat you. BUT if they stomp around, I bet they'd crush things too! I guess it depends on how giant they really are. Like, are they giant human sized? Because then forget the stomping.
Yes BUT with the Snickers, you'd at least have the layers to guide you! And if you started and kind of ate your way down or diagonally, you might miss the caramel and just eat nougat, which wouldn't be terrible. Sticky, but not as sticky. I guess maybe other people would see you stuck in a gummy bear too, and they might help you--but again, with the Snickers, I think you stand a better chance of even just punching your way out! Maybe KitKat would be my ultimate choice to be stuck in, because you have the layers and if you didn't want to eat your way out, you might be able to either punch through or balance on the wafers and then you could sort of push your way out.
