We've been rotating some of E's toys in and out, its helping our living room look less like a plastic explosion, and one thing that came back recently was E's basketball hoop. We were in the basement the other day, and she suddenly started pointing and straining and saying "soccer ball hoop." Turns out that is what she thought the hoop was.
Then, I noticed that at daycare, when we see people playing basketball, she thinks they are playing soccer. I'm not sure she's ever seen anyone play soccer, so I have no idea where the confusion is coming from!
