What is that??

Definetly not a Bike.

LOooks like MARIIJUHHHAWAHNA =]

Picture 3 of 5 might be a sac. I don't see a hair. I'd remove it, if that is the case. If there is no hair, then it's a sac. you can also tell a male from the outer envelope that is segmented - 5 seams where it will open up. Give it a close look. It's easy to tell the difference.

looks like a weed plant. Others already said it, swollen Calyx, when I first grew i thought it was balls or hermi. but its fine.

Female autoflowering cannabis plant! The big "ball" thing is a single female pre-flower calyx that is swollen and over ripe...........completely normal and not a sign of hermies or seeds or anything weird.....in fact it would be weird if your plant did not have them. Without male flowers you can not get seeds and there are no male flowers in any of your pictures, so nothing to be worried about.

On canna, there is a single flower bud that grows at the base of each branch. Just a small cone with two pistilles. This is completely normal. And once dry, If you roll a joint with all the little cones of the whole plant, it makes a more than excellent joint and very strong in THC haha. A pleasure 😉✌️

Maybe nothing, feel it! If it’s a seed inside then you have a hermie. If not then it’s probably a little weird bud formation that popped up
