Tunneled in

Here's a good one for you. I came home and found pieces of cardboard on the counter. They were small, scrap like pieces. Hmmmmm - what is this? Where did it come from? (I asked.)

My husband pipes up and says - 'ya, about that. I tunneled in.'

What? You tunneled in where?

We wanted burgers and it is too hard to get them out of the top of the box. So I tunneled in. I opened the freezer and saw --- it honestly looks like a mouse chewed through the box to the goodies inside.
