Jonah has been getting better at describing things, so rather than "that one" we get complex, if vague descriptions... seemingly always beginning with "the one with...":
"the one with the fire engine" = children's museum we visited over summer vacation
"the one with red and green and blue balls" = ball pit
"the one with the train that goes [hand motions here]" = mindscope race cars
"the one with the red man and the blue man and the green man" = avengers
