Can you suggest a strategy for this refrigerator problem?

I have a side-by-side refrigerator, so the freezer is a narrow vertical column. (I hate it, by the way.)

My son wanted to freeze some freezer gel packs for some purpose or other, so he stuffed about a dozen of them into the narrow space above the ice cube box. They fill it horizontally.

Now that they’re frozen, they present a solid mass welded together by their irregular shapes and the malleability they had when soft. The mass won’t budge.

How in the world are we going to get them out and access the top compartment again? Is there anything short of turning off the fridge and melting everything, in 90-degree weather?
