A squirrel looks up in wonder as it stretches up to reach a bubble.

The effect was created by Ukranian photographer Sergey Polyushko, 36, who spend over five hours in woods in Skhidnytsya, Ukraine photographing the squirrels.

Sergey said, "The squirrels are tame in this forest. We had a bag of nuts and they reached for one while my friend blew bubbles."
