The cantankerous refrigerator, old, rusty and out of his prime, is resting (perhaps confined to the back garden shed and not in the home of the kitchen). With the rising sun, the snowman interrupts the scene seeking refuge inside the refrigerator. He slips as he is slowly melting, making a loud crash that wakes the cantankerous refrigerator from his sleep making him particularly grumpy. A battle of wits occurs as the fridge resists the snowsman's attempts to get inside him. Finally, the sun has reached its peak leaving the snowman to melt in his demise, yet the fridge also meets a similar fate being short-circuited from the water of the melting snow of the snowman.
With a plain background, this helps focus the animation to the central characters while avoiding unnecessary complications by establishing scene and setting. While keeping the cantankerous fridge as the centre in the majority of frames helps to emphasise the focus to the fridge.
A few issues that need to be resolved is that the snowman is perhaps a little 'too' cute, which starts to shift the focus away from the fridge with sympathy in his demise. Shots 1.3 to 1.4 similarly bring attention to the snowman and may perhaps not be necessary to the narrative, as shot 2.5 or 3.2 may work sufficiently to convey the element of the rising sun.
With some further refinement, I believe this could work well in providing an engaging little story while keeping the economy of hand drawing each frame into consideration. Any thoughts and feedback is welcome.
