The three agreed on Harrison, with Tomi saying, “It would take the most time to eat Harrison.” Gavin chimed in, “There’s more to chew on and Harrison would fight back, put up a good fight.” Tomi commented, “It changed how I go into pools, like, I don’t think it changed my relationship with the ocean.”
