R_SQUIR_IMG constants contain Surface objects with left-facing and right-facing squirrel images on them. New Surface objects will be made using the
pygame.transform.scale() function to match the squirrel’s width and height (stored in
After that, the three bounce-related values are randomly generated (except for
sq['bounce'] which is
0 because the squirrel always starts at the beginning of the bounce) and the dictionary is returned on line 8 .
