Sea slugs in bowls

Description: I was taking microscope pictures of a sea slug the other day (Elysia chlorotica), and I was having a hard time because the slug kept leaving the center of the bottom and climbing the walls of the bowl (a flat-bottomed bowl about 8 cm in diameter). No matter how many times I put it in the center, it would always find the shortest route to the edge and climb the wall. I seem to remember I've had this problem with other sea slugs before. So, the question is, why do they do that? What makes the sides of the bowl so appealing? I know it's not the microscope lights, because the slug didn't always crawl up the same part of the bowl.
