Domi encountered a large pit, and from the pit emerged a 3x3 grid with circles, triangles, and squares drawn on the individual squares. Following the sign's instructions, Domi stepped on all the circle-patterned squares to cross the pit and received a lollipop. Then, he stepped on all the square-patterned squares and got some popcorn, and finally, he stepped on all the triangle-patterned squares to obtain an ice cream.
