Different shaped fruit

My SiL got some seedlings from a random FB stranger thinking that she was actually getting fruit! As I have a vegetable plot I ended up with them. However, I’d already planted up my toms fur the season and didn’t have space for them so just put a few in (admittedly too small) pots at the back of the garden. These appear to be a cherry tomato, but the fruit furling at the top looks long and pointy compared the globular fruit lower down. Weird.
