How big are they before adding water?

They come in different sizes - between 4" to 6" long depends on the animal. After a few days in the water they will grow huge.

Can you only get the shark in the lobster

Thanks for your question, Unfortunately, this is sold as a set and we can not ship just two out of the 6. I hope this helps.

what are these made out of?

Some type of foam rubber that slowly absorbs the water and grows significantly in size. They shrink back up when dried out.
