You will need to check if the eyeball has touched each candy.

Loop over all the candies. For each candy, see if the eyeball is touching it (You know where the candy and the eyeball are! How can you tell if they are touching?), if it is touching it, then that candy should disappear.

in the draw candy function or any separate function check the distance between the candy position and the eye position if they touch to delete the candy
